How is the equilibrium yield of C6H12O6 affected by each of the following? 6 CO2(g) + 6 H2O(l) + HEAT C6H12O6(s) + 6 O2(g) (a) increasing PCO2 increases decreases no effect (b) increasing temperature increases no effect decreases (c) removing CO2 increases no effect decreases (d) decreasing the total pressure (TRICKY!!) increases decreases no effect (e) removing part of the C6H12O6 (s), but still in excess no effect decreases increases (f) adding more C6H12O6 (s), even though it is in excess no effect decreases increases
