An equimolar mixture of nitrogen and acetylene enters a steady-flow reactor at 25°C and atmospheric pressure. The only reaction occurring is: N 2 ( g )  +  C 2 H 2 ( g )  → 2HCN ( g ) . The product gases leave the reactor at 600°C and contain 24.2 mol-% HCN. How much heat is supplied to the reactor per mole of product gas?

Please answer in detailed solution. Thank you

The heat capacities for each of the substances involved for a particular reaction are given below. The enthalpy change for the same reaction at 298 Kelvin is -282.987 KJ/mole. From these, answer the questions that follow. Temperature-Dependence of the heat capacities of the Substances for the given reaction + (1/2)02(9) → CO2(9) For the gaseous reaction; CO the heat capacities are: Cp°co P(g) 26.86 + 6.97 x10-3 T - 8.20 x10-7 T2 %3D Cp°o2 25.72 + 12.98 x10-3 T - 38.60 x10-7 T² %3D Cp°co2 26.00 + 43.50 x10-3 T 148.32 x10-7 T² %3D What would be the overall enthalpy change at 1,000 Kelvin (AH @ 1000K, in KJ)?
