For a homogeneous gaseous reaction A⟶3B\mathrm{A} \longrightarrow 3 \mathrm{B}, if pressure after time t\mathrm{t} was Pt\mathrm{P}_{\mathrm{t}} and after completion of reaction, pressure was P∞\mathrm{P}_{\infty} then select correct relation
View answer and explanation
Correct option: D
k=1tln⁡(2P∞3(P∞−Pt))\mathrm{k}=\frac{1}{\mathrm{t}} \ln \left(\frac{2 \mathrm{P}_{\infty}}{3\left(\mathrm{P}_{\infty}-\mathrm{P}_\mathrm{t}\right)}\right)
The correct answer is D (k=1tln⁡(2P∞3(P∞−Pt))\mathrm{k}=\frac{1}{\mathrm{t}} \ln \left(\frac{2 \mathrm{P}_{\infty}}{3\left(\mathrm{P}_{\infty}-\mathrm{P}_\mathrm{t}\right)}\right)) because it correctly relates the rate constant to the pressures at time t and at completion for a first-order reaction.
