ChemistryNEET 2020Integrated rate equations and half-life

Chemical Kinetics

The rate constant for a first order reaction is $4.606 \times 1 0^{- 3} s^{- 1}$ . The time required to reduce 2.0 g of the reactant to 0.2 g is:

A.100 s
B.200 s
C.500 s✓
D.1000 s

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