QUESTION 7

Consider the following reaction at equilibrium. What effect will increasing the pressure of the reaction mixture have on the system?

CuS(s) + O2(g) Cu(s) + SO2(g)

The equilibrium constant will increase.

No effect will be observed.

The equilibrium constant will decrease.

The reaction will shift to the right in the direction of products.

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

QUESTION 8

Consider the following reaction at equilibrium. What effect will increasing the temperature have on the system?

Fe3O4(s) + CO(g) 3 FeO(s) + CO2(g) H°= +35.9 kJ

The equilibrium constant will increase.

The reaction will shift to the right in the direction of products.

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

The equilibrium constant will decrease.

No effect will be observed.

Ques 7) No effect will be observed

When there is an increase in pressure, the equilibrium will shift towards the side of the reaction with fewer moles of gas.

But here there is 1 mole of O2 and 1 mole of SO2 so the gas moles are equal both side so no change.

Ques 8) The equilibrium will shift towards right in the direction of the products.

As the reaction is endothermic so it will require heat so according to Le Chatlier the reaction will proceed forward to overcome the change.
