Question
The following reaction is endothermic. State the effect of each of the following stresses on the position of the equilibrium (state whether the equilibrium shifts to the left, right, or not at all) and then explain.
SO3(g)<-------->SO2(g)+1/2O2(g)
a) SO3(g) is added to the equilibrium mixture without a change in volume or temperature.
b) The volume of the mixture is expanded at constant temperature.
c) The equilibrium mixture is heated.
d) An inert gas is added to the equilibrium mixture without changing the volume.
Explanation / Answer
SO3(g)<-------->SO2(g)+1/2O2(g) ENDOTHERMIC
a) SO3(g) is added to the equilibrium mixture without a change in volume or temperature. --> increase in reactants, therefore the shift goes to PRODUCTS (right)
b) The volume of the mixture is expanded at constant temperature. --> volume increase means Pressure decrease... If P decreases, reactants is favoured. The shift goes to left
c) The equilibrium mixture is heated.--> If you heat, then you increase energy, since this is endothermic, the shift goes to right
d) An inert gas is added to the equilibrium mixture without changing the volume.--> inert gas increases PRessure, Pressure favours reactants, therefore shift goes to left
