Use the equation for the synthesis of hydrogen to answer the following. 10 points.

C (s) + H2O (l) -> CO (g) + H2 (g)

deltaH = + 31.3 kcal/mol carbon

deltaS = +32 cal/(mol•K)


Calculate the energy change (deltaH) when 5.00 g of carbon is consumed.





Calculate the energy change (deltaH) when 2.50 moles of CO is produced.




This reaction is exothermic/endothermic.
