Answer to Question #251806 in Physical Chemistry for nicky

Question

Given the following data: ( ) ( ) ( ) ( ) 2 2 2 CO g H O g CO g H g + → + H ( C) o o  25 = -42.0 kJmol-1 Cp (CO) = 26.8 + 6 x 10-3T JK-1mol-1 Cp (H2O) = 30.1 + 10 x 10-3T JK-1mol-1 Cp (H2) = 28.5 + 2 x 10-3T JK-1mol-1 Cp (CO2) = 26.4 + 42 x 10-3T JK-1mol-1 where T is the thermodynamic temperature, calculate the change in enthalpy for the reaction at 1000 K

Answer 1

Change in enthalpy=4.5×10 ^{-3}
