Consider the reaction: A + 2B(_{(g)} rightleftharpoons ) 2C + D(_{(g)}) ((Delta)H = +ve)
What will be the effect of decrease in temperature on the reaction?
-
A.
Rate of backward reaction will increase -
B.
The equilibrium constant will shift -
C.
Rates of forward and backward reactions are not affected -
D.
Rate of forward reaction will increase
Correct Answer: Option A
Explanation
The given reaction is endothermic, hence, a decrease in temperature will favor the exothermic side which is the backward reaction.
