Introduction:
The reaction rate is the change in concentration of reactant into product per unit of time. Enzyme is a proteinaceous molecule that acts as a catalyst. The enzymes speed up the chemical reaction without being affected by reactions. The enzyme allows the chemical reaction to occur in mild condition. Enzyme neither affects the reaction nor affects the product formation.

- The following equation represents a reversible decomposition: CaCO3(s)CaO(s)+CO2(g) Under what conditions will decomposition in a closed container proceed to completion so that no CaCO3 remains?arrow_forwardThe recycling of polymers represents only one industrial process that allows creating order in one location by creating greater disorder at some other location, often at a power plant. List three other industrial processes that must create disorder in the surroundings to generate the desired material.arrow_forwardRedo Exercise 29 with two particles A and B, which can be distinguished from each other.arrow_forward
- Define the terms product-favored System and reactant-favored System. Give one example of each.arrow_forwardSubstances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?arrow_forwardThe following reversible enzymatic reaction occurs in many areas of the body, but especially in red blood cells. The conversion of water and carbon dioxide into bicarbonate and hydrogen ions occurs through the action of an enzyme called carbonic anhydrase. Use the Law of Mass Action to predict which direction this equation will go under different circumstances. CO2 + H2O ↔ H+ + HCO3- Hyperventilating would increase the loss of carbon dioxide (CO2) from the blood. In what direction would the reaction above go in order to restore equilibrium? Left or right?arrow_forward
- 12. For the endothermic reaction HBR9) + heat > Br2(9) + H2(g) when the temperature is increased which direction will the reaction shift? a. Right (products) b. Left (reactants) c. roughly equal amounts of products and reactants are present d. no change in amounts producedarrow_forwardO 11. The decomposition of ozone in the upper atmosphere to dioxygen occurs by a two-step mechanism. The first step is a fast reversible step and the second is a slow reaction between an oxygen atom and an ozone molecule: Step 1: Step 2: O3(g) = 02(8) + O(g) O3(g) + 0(g) → 202(g) Fast, reversible, reaction Slow a. Which is the rate determining step? b. Write the rate equation for the rate-determining step. Write the rate equation for the overall reaction. с. The rate equation for the reaction of nitrogen dioxide and carbon monoxide in the gas state to form carbon dioxide and nitric oxide is represented by the equation: 12. NO2(g) + CO(g) → NO(g) + CO2(g) The following data were collected at 125°C:e Experiment 1 Experiment 2 Experiment 3 Initial [NO2] mol L 5.0 x 104 5.0 x 104 1.5 x 10-3 Initial [CO] mol L- 1.6 x 10-2 3.2 x 102 3.2 x 10-2 Initial rate mol L'min 1.7 x 10-7 1.7 x 10-7 1.5 x 10-6 What is the order with respect to NO2? b.
