Question

# At a constant pressure P, the plot of volume (V) as a function of temperature(T) for $$2$$ moles of an ideal gas gives a straight line with a slope $$0.328$$L $$K^{-1}$$. The value of P(in atm) is closest to :[Gas constant, $$R=0.0821$$L atm $$mol^{-1}$$ $$K^{-1}$$].

A
0.25
B
0.5
C
1.0
D
2.0

Solution

## The correct option is B $$0.5$$From Ideal Gas Equation we have,Slope of $$V$$vs $$T$$ plot = $$nR/P$$$$2\times 0.0821/P=0.328$$$$P=0.5atm$$Chemistry
