A1 (Complete this on your Free Response paper) Consider the reaction:               C2H5OH(l) + 3O2(g) –> 2CO2(g) + 3H2O(l);                ∆H = –1.37 x 103 kJ   a) What type of reaction is this? b)  Is this reaction exothermic or endothermic?  Justify your answer.  c) How would the ∆H change if 3H2O(g) was produced instead of 3H2O(l)? d)  If you react 4.5 g of ethanol, how much heat would be involved?  Show your work for full credit.
