Introduction to Integrated Rate Laws Learning Goal: To understand how to use integrated rate laws to solve for concentration. A car starts at mile marker 145 on a highway and drives at 55 mi/hr in the direction of decreasing marker numbers. What mile marker will the car reach after 2 hours? This problem can easily be solved by calculating how far the car travels and subtracting that distance from the starting marker of 145. 55 mi/hr x 2 hr = 110 miles traveled milemarker 145 -110 miles milemarker 35 If we were to write a formula for this calculation, we might express it as follows: milemarkero- (speed x time) milemarker where milemarker is the current milemarker and milemarker, is the initial milemarker. Similarly, the integrated rate law for a zero-order reaction is expressed as follows: [A]orate x time [A] or since rate k[A] = k Azero-order reaction (Figure 1)proceeds uniformly over time. In other words, the rate does not change as the reactant concentration changes. In contrast,…

Sample Designs: Test one group against another group of experiment on the same reaction time test Compare the reaction times of the same people under two different conditions, like after exercise A test subject attempts to grab the ruler as it is dropped, the number on the ruler where the fingers grasp it can be used to judge reaction time Digital reaction time tests are easy to find with a google search You can also install an app on your phone that can measure reaction time (useful if you want to test subjects outside of class) C) How will you gather data? Will you take averages?

Explain how  the rate of reaction rate in pressure cookers was increased by including these subtopics:1. Chemical reaction(s) involved with chemical equation(s) 2. Reactants, products, and possible catalysts involved in the chemical reaction 3. Explain with collision theory and energy potential diagrams: how the rate of reaction is affected by temperature, surface area, nature of reactants, concentration, etc. by using collision theory? 4.Discuss whether the reaction is endothermic or exothermic (use Hess’s Law, Le Châtelier’s Principle, or Kinetic Molecular Theory to explain in increasing rate of reaction and relevance by including all 4 required subtopics )
