PV=RT (1)

Here,

P is pressure of gas.

V is molar volume of gas.

T is absolute temperature of gas.

R is universal gas constant.

The formula to calculate pressure of one mole of gas is as follows:

P=RT(V−b)−aV2 (2)

Here,

P is pressure of gas.

V is volume of gas.

T is absolute temperature of gas.

R is universal gas constant.

Answer 8

(a)

Expert Solution

Explanation of Solution

Rearrange equation (1) to calculate P.

P=RTV (3)

Substitute 30.0 L for V, 298 K for T, and 8.20574×10−2 L⋅atm⋅K−1⋅mol−1 for R in equation (3).

P=(8.20574×10−2 L⋅atm⋅K−1⋅mol−1)(298 K)30.0 L=0.82 atm

Substitute 30.0 L for V, 298 K for T, 8.20574×10−2 L⋅atm⋅K−1⋅mol−1 for R, 0.2452 bar⋅L2⋅mol−2 for a and 2.65×10−2 L⋅mol−1 for b in equation (2).

P=((8.20574×10−2 L⋅atm⋅K−1⋅mol−1)(298 K)(30.0 L−2.65×10−2 L⋅mol−1))−(0.2452 bar⋅L2⋅mol−2(30.0 L)2)=0.82 atm

Pressure exerted by 1.00 mol H2 at 298 K and 30.0 L with help of ideal gas equation and van der Waals equation is 0.82 atm and 0.82 atm respectively.
