Answer to Question #250039 in Physical Chemistry for girl

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}
