The overall reaction for photosynthesis can be represented by the following equation:
6 CO₂(g) + 6 H₂O(l) ⇌ C₆H₁₂O₆(s) + 6 O₂(g)
The enthalpy change for this reaction is 2802 kJ.Which of the following changes in condition will shift the equilibrium to the right?

According to Le Chatelier's principle, if a stress is applied to a system at equilibrium, the system will react in such a way as to counteract the stress and re-establish equilibrium. Increasing the temperature is a stress that will shift the equilibrium to the side with the endothermic reaction, meaning the reaction will shift to the right to consume the excess heat. This will cause an increase in product concentration and shift the equilibrium to the right. None of the other options will result in a shift to the right.
