1g of graphite is burnt in a bomb calorimeter in excess of oxygen at 298 K and 1 atmospheric pressure according to the equation: C (graphite) + O 2 (g) → CO 2 (g) During the reaction, temperature rises from 298 K to 299 K. If the heat capacity of the Bomb Calorimeter is 20.7kJ/K, what is the enthalpy change for the above reaction at 298 K and 1 atm?

Options

  1. A–1.86 ×10 2 kJ mol –1
  2. B–4.52 ×10 2 kJ mol –1
  3. C–2.48 ×10 2 kJ mol –1
  4. D–3.68 ×10 2 kJ mol –1

Correct answer

C. –2.48 ×10 2 kJ mol –1
