For the reaction below, the constant pressure heat of reaction is qp = −2451 kJ mol−1 at 25 °C. What is the constant volume heat of reaction, qV, at 25 °C? 12 CO(g) + 25 H2(g) ⟶ C12H26(l) + 12 H2O(l) Enter your answer in kJ mol−1

Consider the following thermochemical equations. Reaction ΔrH° / kJ mol−1 HBr(g) ⟶ H(g) + Br(g) 365.7 H2(g) ⟶ 2 H(g) 436.0 Br2(g) ⟶ 2 Br(g) 193.9 What is ΔrH° for the reaction below, in kJ mol-1? HBr(g) ⟶ ½ H2(g) + ½Br2(g)

For the reaction below, ΔrH° = −3908.7 kJ mol−1. What is the standard enthalpy of formation of C7H8(l) in kJ mol-1? C7H8(l) + 9 O2(g) ⟶ 7 CO2(g) + 4 H2O(l) Data: Substance Standard enthalpy of formation (in kJ mol−1) CO2(g) −393.5 H2O(l) −285.9
