QUESTION 10 A reaction A→B has a second order rate law with k= 8.75×10-2Lmol-1s-1 at 30°C. Calculate the time (s) required for the concentration of A to change from 0.360 moll-1 to 0.025molL-1. Please round to nearest integer. For example, 10.7 is 10. 3600 QUESTION 11 Regarding the reaction described above, if the temperature dependence of rate constant obeys Arrhenius equation and the activation energy is 60.5kJ mol-1, calculate the rate constant (s) at 50°C. Please round to two decimal places.
