A reaction AB has a second order rate law with k=8.75102Lmol1s1 at 30C. Calculate the time (s) required for the concentration of A to change from 0.360molL1 to 0.025molL1. Please round to nearest integer. For example, 10.7 is 10. Regarding the reaction described above, if the temperature dependence of rate constant obeys Arrhenius equation and the activation energy is 60.5kJmol1, calculate the rate constant (s) at 50C. Please round to two decimal places
