Calculate the energy required to heat 1.30 kg of ethane gas (C2H6) from 27.0°C to 78.0°C first under conditions of constant volume and then at a constant pressure of 2.00 atm. Calculate ?E, ?H, and w for these processes. (See Table 9.1 for relevant data.) Cv J/K mol of C2H6 is 44.60 Cp J/K mol of C2H6 is 52.92 What is delta E, Delta H and W at constant volume and constant pressure in KJ
