Q. What is the effect of having the pressure by doubling the volume on the following system at 500$℃$? $H_{2}(g) + I_{2}(g) \rightleftharpoons 2HI(g)$
A) Shift to reactant side
B) Shift to product formation
C) Liquefaction of HI
D) No effect
Explanation
(d)
The reaction in which number of moles of reactants= number of moles of products are not effected by change in pressure or volume.
$H_{2}(g) + I_{2}(g) \rightleftharpoons 2HI(g)$
$\therefore$ Number of moles of reactant = number of moles of products
2=2
$\therefore$ This reaction is not effected by change in pressure or volume.
