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

A) increase the pressure of O2
B) increase the temperature
C) remove one-half of C6H12O6(s)
D) remove CO2 by reaction with CaO(s)

B & C

Explanation:

Because the forward reaction results in a positive change in enthalpy, this reaction is endothermic – it takes energy from the environment. Therefore, the forward reaction will be favored if there are an increase n temperatures

Forward and reverse reactions are usually balanced. Removing a product (C6H12O6 in this case) as it is formed, favors the forward's reaction.  This is because the process that results in a reduction in pressure of the system is favoured in the reaction.
