In a 1 st order reaction, reactant concentration $C$ varies with time $t$ as :

A
$\frac{1}{\mathrm{C}}$ increases linearly with $t$
Correct answer
B
$\log \mathrm{C}$ decreases linearly with $t$
C
C decreases with $\frac{1}{t}$
D
$\log \mathrm{C}$ decreases with $\frac{1}{t}$

Hence, the correct answer is option: 'B'.
