Q7. One mole of N2 at 293.5 K and 8.11 bar undergoes a transformation to a state described by 418 K and 1.24 bar. Calculate the entropy change for the process (J/K) if Cp is as follows: C subscript P comma m end subscript equals 30.81 minus 11.87 space cross times 10 to the power of negative 3 end exponent T plus 2.3968 space cross times 10 to the power of negative 5 end exponent T squared minus 1.0176 cross times 10 to the power of negative 8 end exponent T cubed space J divided by m o l minus K Ans. in 3SFs
