Slope of the graph between rate (Y-axis) and [A] (X-axis) for the first order reaction is equal to
- $\mathrm{k}$
- $\frac{2.303}{\mathrm{k}}$
- $\frac{\mathrm{k}}{2.303}$
- $-\mathrm{k}$
Solution
For first order reaction,
Rate law is
$\begin{aligned}
& \text { Rate }=\mathrm{k}[\mathrm{A}]^1 \\
& \mathrm{y}=\mathrm{m} \cdot \mathrm{x} \\
& \text { slope }=\mathrm{m}=\mathrm{k}
\end{aligned}$Asked in: MHT CET 2021 (21 Sep Shift 1)
