Rate of Reaction

Q. In the rate constant for the forward reaction in N2O4(g) ⇋ 2NO2(g) is larger than the rate constant for the reverse reaction, will the constant in [NO2]^2/[N2O4] = kf/kr be greater than 1 or smaller than 1?

Rate of Reaction

Q. The enzyme Y catalyzes the elementary reaction AB → A + B An enzyme concentration of 1.0 μM Y can convert a maximum of 0.5 μM AB to the products A and B per second. Note: Since the concentrations of species in the cytoplasm of cells is small, the concentration unit of micromolar (μM or 10^-6 M) is used for consistency with biochemical systems. What will happen when each of the following is added to a solution that contains 1.0 μM Y and 0.8 μM AB? Drag each item into the appropriate bin.

Rate of Reaction

Q. Which of the following correctly applies to a catalyst? A. They do not actually participate in the chemical reaction and therefore are unchanged at the end of the reaction. B. They provide an alternate lower energy mechanism by which the reaction proceeds. C. They must be in the same phase as the reactants in the chemical reaction. D. Biological catalysts are proteins called substrates. a) B only b) A and B only c) A and D only d) B and C only
