How does increasing the temperature affect the yield of products of a reaction at equilibrium, where the forward reaction is exothermic?

The position of equilibrium changes after the temperature increases according to Le Chatelier's principle, which states that if a change is applied to a system in equilibrium, then the position of equilibrium will move to counteract that change. As the forward reaction is exothermic, equilibrium will shift left in the endothermic direction to reduce the temperature, as the endothermic reaction will absorb the heat that has been added. As the system now favours the reverse reaction, the yield of products would therefore decrease.The main marking points in this answer are stating whether equilibrium moves left or right, the reason for this (whether it moves in the endothermic or exothermic direction), and whether the yield of products would increase or decrease.
