The compressibility factor of a gas is given by (where, V1 = actual volume of the gas V2 = gas volume predicted by ideal gas law)____________________?
Correct answer: A. V1/V2
- A. V1/V2
- B. V2/V1
- C. V1 - V2
- D. V1.V2
Explanation
The compressibility factor is Z = PV/RT. At the same pressure and temperature, the ideal-gas volume is V2 = RT/P, so Z equals the ratio of actual volume V1 to ideal-gas volume V2.
