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 in equilibrium, the system will shift in the direction that counteracts the stress. In this case, increasing the temperature will increase the kinetic energy of the molecules in the system leading to an increase in the rate of the forward reaction, which will shift the equilibrium to the right. Increasing the pressure of gas or adding water or solid product will not affect the equilibrium as they are not part of the gaseous reactant or product. Adding more solid product will shift the equilibrium to the left according to Le Chatelier's principle.
