Question
For the endothermic reaction where tert-butyl alcohol decomposes into water and isobutene: (CH_3)_3COH(g) (CH_3)_2CCH_2(g) + H_2O(g) A reaction vessel contains these compounds at equilibrium. What will happen if the volume of the container is reduced by 50% at constant temperature? A) The forward reaction will proceed to reestablish equilibrium. B) The equilibrium constant will increase. C) The reverse reaction will proceed to reestablish equilibrium. D) No change occurs. E) The equilibrium constant will decrease.Explanation / Answer
(ch3)3COH(g) <====> (ch3)2CCH2(g) + H2O(g)
at equilibrium
if the volume of system is reduced to half, the pressure of the system increases.
in order to re-establish the equilibrium, reaction shifts towards less no of moles side.
so that backward reaction is favourable.
answer: C
