Explanation / Answer

when the volume of an equilibrium mixture of gases is increased, the pressure of the system is decreased.

So, a net change occurs in the direction that produces more moles of gas.

2 H2S(g) + 3 O2(g) 2 H2O(g) + 2 SO2(g)

In the reaction, the number of moles of reactants is 5 and the total number of moles of products is 4.

when the volume of above reaction increases, a net chnage in the direction that produce more mole of gas that is reactant side.

therefore, The reaction will shift to the left in the direction of reactants.
