Consider the reaction \( \mathrm{A(s) + 2B(g)... | JAMB UTME - Chemistry - 2019

Question 1 Report

Consider the reaction

$ \mathrm{A(s) + 2B(g) \rightarrow 2C(aq) + D(g)} $

What will be the effect of a decrease in pressure on the reaction?

the equilibrium will shift

rate of forward reaction will increase

rate of backward reaction will increase

rates of forward and backward reaction are not affected

Answer Details

Given: The equation below

A $_{(s)}$ + 2B $_{(g)}$ → 2C $_{(a q)}$ + D $_{(g)}$

Since we have a higher number of moles of gaseous species on the LHS, i.e 2, a decrease in pressure will favor the forward reaction.

Consider the reaction \( \mathrm{A(s) + 2B(g) \rightarrow 2C(aq) + D(g)} \) What will be the effect of a decrease in pressure on the reaction?
