Calculate the standard entropy change for the following reaction at 25C

H20(g) + C (graphite) (s)---> H2(g) + CO (g)

Delta Srxn= J/K

rearrange the second equation to obtain CO on the other side of the equation(Delta H is now reversed for that equation, 556.0kJ) do the same for the third equation to obtain H2 on the other side; swith Delta H Combine all three equations, and cancel like terms: C(s)+O2(g)+2CO2(g)+2H2O(g)=CO2(g)+2CO(
