Q.5
Determine the standard enthalpy change of reaction at 1200 K for the gas phase reaction
CO + H20 - CO2 + H2
At 298.15 K, AHCO,(= -94.0518 kcal/mol AH.CO(=-26.4157 kcal/mol
Session: 2020-21
AH; H2000)=-57.7979 kcal/mol
The standard heat capacity of various components is given by Co = a +bT + cT + T.
where Cp is in cal/mol-K and T is in K
