Question: the heat of reaction for one mol of cac2s cac2...

Question details

The heat of reaction for one mol of CaC2(s) CaC2 (s)+ 5H2O (l) = CaO (s) +2CO2 (g) + 5H2( g) is equal to 76.4 kJ. You charge 92.3 grams of CaC2 (molar mass of CaC2= 64.1 g/mol) and liquid water into a rigid container at 25°C, heat the container until the calcium carbide reacts completely, and cool the products back down to 25°C, condensing essentially all the consumed water. Calculate the net amount of heat in kJ that must be transferred to or from the reactor. (hint: you need to calculate the internal energy first).
