Question

At equilibrium of the reaction
`2X(g)+Y(g) hArr X_(2)Y(g)`
the number of moles of `X_(2)Y` at equilibrium is affected by the
A. temperature and pressure
B. Temperature only
C. pressure only
D. temperature , pressure and catalyst.

Answer 1

Correct Answer - A
Backward reaction is a dissociation reaction and hence endothermic . Thus, forward reaction is exothermic and proceed with decrease in number of moles of gaseous molecules. Hence high pressure and high temperature will favour the forward reaction.
