Given a reaction with the following data, calculate the rate constant (k) of the reaction:2 A + 3 B → CAt a particular temperature, the initial concentration of A was 0.2 M and the initial concentration of B was 0.5 M. After 30 minutes, the concentration of A decreased to 0.1 M while the concentration of B decreased to 0.3 M. The reaction is second order with respect to A and first order with respect to B.
