(a) Cp = Cv + 1.5 R

(b) Cp = Cv + R

(c) Cp = Cv – 1.5 R

(d) Cp = Cv – R

I have been asked this question during a job interview.

My enquiry is from Heat Capacity topic in division Energy Balances of Chemical Process Calculation

Answer 1

Correct option is (b) Cp = Cv + R

Explanation: For an ideal gas: Cp = Cv + R.
