Question

For the reaction A ---> 2 B + C, thefollowing data are obtained for [A] as a function of time: t = 0min, [A] = 0.800M; 8min, [A] = 0.700 M; 24 min, [A] = 0.550 M; 40 min, [A] = 0.450 M;90 min, [A] = 0.280 M.

(a) Is the reaction first order or second order? Show evidencethat conclusively supports your claim.

(b) What is the value of the rate constant, k?

(c) Calculate the rate of formation of B at t = 30 min.
