Rate equation

Rate equation and order of reactant: The rate of reaction is defined as how fast the reactant is converted to the product and it is measured in moldm-3s-1 Rate=(change in concentration(〖moldm〗^(-3)))/(time taken (s)) , the unit of rate = moldm-3s-1 Rate = k [A]x [B]y [C]y Orders of the reaction must be taken in to account when writing a rate equation. Where A, B and C are reactant, x, y and z are the orders of the reaction with respect to A, B and C. In my investigation I will vary the concentration

Determination of a Rate Equation Rate equation has the form rate = k [A]x[B]y which shows how the rate of a chemical reaction depends on the concentration of the reactants (A&B) and the rate constant k. The rate equation normally indicates what species are involved in the rate-determining step and how many species are involved. A rate equation is used to describe how the concentration of a product increases or the concentration of the reactants decreases with time, the equation also indicates how

an unknown rate law equation. The lab is also performed to create the rate law of the equation. This is done through varying the amount and concentration of the reactants in the equation. These two variables can have a drastic impact on the speed that the reaction develops at It also does this by varying the dependence of the reactants throughout the trials. The order of the equation is found by finding the correlation between the concentration of the reactants and the reaction rate. Determining

Clock reactions can be highly useful to investigate rates of reaction as the rate of the colour change may differ due to varying factors. The reaction rate of a chemical reaction can be defined as the speed in which the reaction occurs. The speed

chemical reaction is increased then the rate at which product is being produced in the reaction will also increase. This is because as temperature increases kinetic energy increases which causes the molecules to speed up. As molecules speed up there are more collisions which also means there are more successful collisions. The more successful collisions that there are the more product that is produced. 2. If the concentration of a reactant is increased then the rate at which product is being produced

the reaction rate. Therefore decreasing the temperature will decrease the rate of the reaction. From the results given in Tables 2 and 3 it shown that every time the concentration is halved the time is increased. When the concentrations of both KIO3 and NaHSO3 are decreased the time has increased, some concentrations having a higher increase than others. In each concentration decrease the time is at least doubled from the previous concentration time, which is therefore increasing the rate of the reaction

Christaller's Central Place Theory Introduction Central Place Theory (CPT) is an attempt to explain the spatial arrangement, size, and number of settlements. The theory was originally published in 1933 by a German geographer Walter Christaller who studied the settlement patterns in southern Germany. In the flat landscape of southern Germany Christaller noticed that towns of a certain size were roughly equidistant. By examining and defining the functions of the settlement structure and the size of

physiological functions including growth, respiration, and energy generation (adenosine triphosphate synthesis). Cell death results in the destruction of protein thiols and production of free radicals. Compounds such as surfactants can enhance and speed up the rate of inhibition and death. (Williams, 2007) The interaction of isothiazolone biocides with microbial cells proceeds via several sequential reactions. Initially, a biocide molecule reacts with a thiol group to form a disulphide linkage with the biocide

Case Report: Kristen’s Cookie Company 1. Assuming that the order contains a dozen of cookies, the time to take a rush order is the sum of cycle times for each activity: 0+6+2+9+1+0+5+2+1=26 min. 2. Assuming a two dozens order, we have to consider that for the first dozen, my roommate can start backing after I have spooned the cookies on the tray. However when backing the second order he simultaneously cools and then packs the cookies from the first order. I can start mixing the second batch

Change is a double-edged sword (Fullan, 2001). Change is a word that might inspire or put fear into people. Leadership is challenging when it comes to dealing with change and how individuals react within the organization to the change. Marzano, McNulty, and Waters (2005) discuss two orders of change in their book School Leadership that Works; first and second. Fullan (2001) also adds to the discussion in his book Leading in a Culture of Change, with regard to understanding change. In Change Leadership
