Question

3. In photosynthesis, the following reaction takes place:
6 CO2(g) + 6 H2O(l) → 6 O2(g) + C6H12O6(s) ∆H = 2801 KJ
a. Calculate ∆H when one mole of CO2 reacts.
b. How many kilojoules of energy are liberated when 15.00g of glucose, C6H12O6, is burned in oxygen?

Answer 1

∆H of 1 mole CO2 466.83 kJ

15 g glucose is 232.48 kJ
