What will happen if more heat is applied to the following system at equilibrium? X2(g) + 3Y 2(g) ⇌ 2XY3(g); ∆H =-kJmol -1
- the yield of XY 3 will decompose
-
more of XY3 will decompose
- More of X2 will react
- the forward reaction will go to completion
The correct answer is: B
Explanation
If more heat is applied to an exothermic reaction in equilibrium, it means temperature is increased, this will however, cause the equilibrium shift to the left. This means the product will decompose to produce more of the reactants on the LHS. i.e XY\(_3\) will decompose.
