For two reactions, I: A to B """Rate constant"=k_(1)sec^(-1) II: C to D """Rate constant"=k_(2) M^(-1)sec^(-1) Starting with initial concentration of 1M each, time taken to reach to 0.5M is same, then, identify the correct options.

Answer»

`k_(1)gtk_(2)`
`k_(1)lt k_(2)`
Rate of FIRST reaction at 0.5M concentration gt rate of second reaction at 0.5M concentration.
INITIAL rate of first reaction lt initia rate of second reaction.

Answer :B::C::D
