State heated at constant volume until its pressure increases

Reference no: EM13333153

A) (25 pts) Consider a 1.00 mol sample of acetylene (C2H2) is allowed to undergo the following two step, reversible process: the gas is a) first heated at constant volume until its pressure increases from 2.5 atm to 3.2 atm and then b) cooled at constant pressure until its volume changes from 4.0 L to 2.2 L. Given that for acetylene that CP,m = 43.93 J•mol-1 • K-1 and that 1 L-atm = 101.325 kJ, determine the following: i) the work for step a) of the process (in kJ ) ii) the work for step b) of the process (in kJ) iii) the heat associated with step a) of the process (in kJ ) iv) the heat associated with step b) of the process (in kJ) v) the change in internal energy (?E) for the entire process (in kJ)
