Question

1) Consider the reaction Under certain specified conditions, the rate of the reaction is: (a) What is the order of the reaction with respect to the concentration of oxygen? (b) What is the overall order of the reaction? (c) If the concentration of hydrogen is doubled, will the rate of the reaction remain unchanged double, quadruple, or be halved? 2) For the reaction the rate of the reaction was increased by a factor of eight when the concentration of both NO and Cl; were doubled. When only the concentration of Cl, was doubled, the rate of the reaction increased by a factor of two. Write the rate equation for the reaction. Explain your answer 3) Consider the reaction of persulfate ion and lodide ion These substances were mixed in various quantities at 25 C and the following rate data obtained initial rate 1.23 x 10 1.25 x 10-a | 9.99 x10, ↓ 1.25 x 10 2.03 x 10 2.40x10시160x104 x10+ 2.50 x1o- (a) Use the method of initial rates to find the onder of the reaction with respect to the concentration of persulfate ion (b) Find the order of the reaction with respect to the concentration of lodide ion. (c) Write the rate equation for the reaction (d) Calculate the rate constant, k, for each experiment and the average k, (e) Calculate the rate of the reaction if the concentration of persulfate ion is 3.68 x 10-3 M and that of iodide lon is 1.73 x 10-1 M.
