1. (8 pts) Virtually every pchem textbook has a table of enthalpy values for 25°C. One use for these may be to calculate the enthalpy fora phase change such as boiling. However, not t0o many compounds boil at 25°C. You are going to calculate the percent difference between the heat of vaporization of ethanol using data for 25°C and that at its boiling point of 78°C. a) Write the chemical equation that shows the vaporization of 1 mol of ethanol...
