Question 21 POST_UTME_DELSU • 2022 • CHEMISTRY • objective

The van der Waals equation is given by \( left\( P + \frac{a}{V^2} \right \ \) \( V - b \) = RT ). If the gas cons\tant R = 0.08206 L atm K^{-1} mol^{-1}, the van der Waals cons\tant 'a' for a gas is 3.61 L^2 atm mol^{-2}. Calculate the value of the van der Waals cons\tant 'b' for the gas, given that the pressure P = 1 atm, the temperature T = 300 K, and the volume V = 22.4 L.

Answer Options

A. 0.0427 L mol^{-1}
Correct Answer B. 0.0437 L mol^{-1}
C. 0.0447 L mol^{-1}
D. 0.0457 L mol^{-1}
Correct Answer
B
Correct Option:
0.0437 L mol^{-1}
