Chemical Kinetics

The rate constant for a first order reaction is 4.606×10−3 s−14.606 \times 10^{-3}\ \mathrm{s^{-1}}. The time required to reduce 2.0 g of the reactant to 0.2 g is:

  1. A.100 s
  2. B.200 s
  3. C.500 s✓
  4. D.1000 s

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