Chemical Kinetics

If the rate constant for a first-order reaction is kk, the time tt required for 99% completion of the reaction is given by:

  1. A.t=0.693/kt = 0.693/k
  2. B.t=6.909/kt = 6.909/k
  3. C.t=4.606/kt = 4.606/k✓
  4. D.t=2.303/kt = 2.303/k

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
