Which one of the following conditions will favor the maximum formation of the product in the reaction?

A2(g)+B2(g)⇌X2(g)ΔrH=−XkJ{A}_{2}\left(g\right) + {B}_{2}\left(g\right) ⇌ {X}_{2}\left(g\right){\Delta}_{r}H = - XkJ

Options

  1. AHigh temperature and high pressure.
  2. BLow temperature and low pressure.
  3. CLow temperature and high pressure.
  4. DHigh temperature and low pressure.

Correct answer

C. Low temperature and high pressure.

Step-by-step solution

logk2k1=\DeltaH2.303K(1T1−1T2)log\dfrac{{k}_{2}}{{k}_{1}} = \dfrac{\text{\Delta}H}{2 .303 K}( \dfrac{1}{{T}_{1}} - \dfrac{1}{{T}_{2}} )

∴\DeltaH=−ve∴ \text{\Delta}H = - ve and for the maximum formation of the product k2>k1{k}_{2} > {k}_{1} hence, T1>T2{T}_{1} > {T}_{2} mean temperature should decrease

\Deltang=−ve\text{\Delta}{n}_{g} = - ve

kp∝1p{k}_{p} ∝ \dfrac{1}{p} on increasing pp reaction goes in forward direction.
