Given the same reactant concentrations, the reaction CO (g) + CI₂ (g) —> COCI₂ (g)
at 250°C is 1.50x10^3 times as fast as the same reaction at 150°C. Calculate the activation energy for this reaction. Assume that the frequency factor is constant.
Consider the reaction
A—> B
The rate of the reaction is 1.6 x 10 ^-2 m/s when the concentration of A is 0.35 M. Calculate the rate constant if the reaction is (a) first order in A and (b) second order in A.
The rate constant for the second-order reaction 2 NOBr(g) —> 2 NO (g) + Br₂(g)
is 0.80/M.s at 10°C. (a) Starting with a concentration of 0.086 M, calculate the concentration of NOBr after 22 s. (b) Calculate the half-lives when [NOBr]₀= 0.072 M and [NOBr]o = 0.054 M
