a) The reaction A(aq) → B(aq) is a first order reaction with respect to A(aq). The concentration of A(aq) is reduced from 0.892 M to 0.505 M in 3.05 minutes. What is the half-life, in seconds, of this reaction?

b) The reaction A(aq) → 2 B(aq) is a second order reaction with respect to A(aq). Its activation energy is 49.5 kJ/mol. When the concentration of A(aq) is 0.100 M and the temperature is 25.0oC, the rate of reaction is 0.333 M/s. What is the rate of reaction when we increase the concentration of A(aq) to 0.216 M and we raise the temperature to 52.9 oC?
