Question

28. The van der Waals equation of state for a real gas is = nRT In this equation, the van der Waals constant, a, represents a correction for a. a deviation in the measured value of P from that for an ideal gas due to the finite volume of space occupied by molecules of a real gas. b. a deviation in the measured value of P from that for an ideal gas due to the attractive forces between the molecules of a real gas. c. a deviation in the measured value of P from that for an ideal gas due to the finite mass of the molecules of a real gas.

Explanation / Answer

answer is b) the vanderwalls constant a is correction in the measurement of P from an ideal gas due to the attractive forces between the molecules of real gas . in the ideal gas there is no interaction between the molecules , so the pressure is more , whereas in real gas there are interaction between the molecules so the overall pressure decreases
