For reaction ArarrB, the rate constant k_(1)=A_(1)^(-Ea_(1//(RT))) and for the reactio XrarrY, the rate constant k_(2)=A_(2)^(-Ea_(1//(RT))) . If A_(1)=10^(8),A_(2)=10^(10) and E_(a_(1))=600 cal /mol, E_(a_(2))=1800 cal/mol then the temperature at which k_(1)=k_(2) is (Given :R=2 cal/K-mol)

Answer»

1200 K
`1200xx4.606 K`
