The overall photosynthesis reaction is 6 CO₂(g) +6 H₂O(l) → C₆H₁₂O₆(aq) + 6 O₂(g), and ΔH° = +2802 kJ. Suppose that the reaction is at equilibrium. State the effect that each of the following changes will have on the equilibrium composition: tends to shift toward the formation of reactants, tends to shift toward the formation of products, or has no effect. 

(a) The partial pressure of O₂ is increased. 

(b) The system is compressed. 

(c) The amount of CO₂ is increased. 

(d) The temperature is increased. 

(e) Some of the C₆H₁₂O₆ is removed. 

(f) Water is added. 

(g) The partial pressure of CO₂ is decreased.
