A graph is plotted between PVm (along Y-axis) and P (along X-axis) at 27°(Vm being the molar volume of an ideal gas). The intercept of the graph at Y-axis is (R = 0.082 atm LK-1 mol-1)
(a) 22.4 atm L mol-1
(b) 24.6 atm L mol-1
(c) 24.6 atm LK-1 mol-1
(d) None of these

Correct answer: (b) 24.6 atm L mol-1
Explanation:
The graph is a straight line parallel to the axis of pressure with intercept
= PVm = RT = 0.082 atm LK-1 mol-1 x 300 K
= 24.6 atm L mol-1
