Question:medium
For a first order reaction, A(g) $\rightarrow$ B(g) at 35 $^\circ$C, the volume of "A" left in the reaction vessel at various times are given below. [Given data: $\log(5/4) = 0.0969$]

Show Hint
For first-order reactions, the half-life is independent of the initial concentration/volume. You can check $k$ at different intervals ($t=20, 30$) to verify consistency.
