Question

In the ideal gas equation, the value of universal gas constant depends on :

• A. Nature of the gas
• B. Pressure of the gas
• C. Temperature of the gas
• D. Unit of measurement

Answer 1

Answer: (D)

Unit of measurement

According to the ideal gas equation,

$PV=nRT$

As a unit of measurement changes, the value of universal gas constant (R) changes as -

$R=8.314\frac{J}{K.mol}$

or,

$R=0.0821\frac{L.atm}{K.mol}$

Hence, option $\left(D\right)$ is correct.
