B

Reaction 2 is more exothermic than reaction 1

C

Reaction 2 is more endothermic than reaction 1

D

Reaction 2 is fast compared to reaction 1

Activation energy (E_(a)) and rate constants ( k_(1) and k_(2) ) of a chemical reaction at two different temperatures ( T_(1) and T_(2) ) are related by

For the two parallel reactions A overset(k_(1)) rarr B and A overset(k_(2)) rarr C , show that the activation energy E' for the disappearance of A is given in terms of activation energies E_(1) and E_(2) for the two paths by E' =(k_(1)E_(1)+k_(2)K_(2))/(k_(1)+k_(2))
