In the following first order competing reactionsthe ratio of  k1k2 , if only  94%  of  A  have been reacted whereas  50%  of  C has been reacted, is

A first order reaction has the rate constant,  k=4.6×10−3 s−1. The number of correct statement/s from the following is/are Given: log 3=0.48.A. Reaction completes in 1000 s.B. The reaction has a half-life of 500 s.C. The time required for 10% completion is 25 times the time required for 90% completion.D. The degree of dissociation is equal to (1−e−kt).E. The rate and the rate constant have the same unit.

In which of the following case, does the reaction go fartiest to completion ifKc=102Kc=10Kc=10−2Kc=1
