Question on: JAMB Chemistry - 2019
Consider the reaction
A\(_{(s)}\) + 2B\(_{(g)}\) → 2C\(_{(aq)}\) + D\(_{(g)}\)
What will be the effect of a decrease in pressure on the reaction?
A
the equilibrium will shift
B
rate of forward reaction will increase
C
rate of backward reaction will increase
D
rates of forward and backward reaction are not affected

Correct Option: B
Given: The equation below
A\(_{(s)}\) + 2B\(_{(g)}\) → 2C\(_{(aq)}\) + 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.
