Question

which one of the following is not hte value of R?​

Answer 1

$\huge \mathcal\red{Answer}$

9.8 kcal K

−1

mol

−1

is not the value of R.

1.99 cal K

−1

mol

−1

is the value of R.

Note:

In the equation of state of an ideal gas PV=nRT, the value of universal gas constant would depend only on the units of measurement. It is independent of the nature of the gas, the pressure of the gas and the temperature of the gas.

For example, R=8.314J/mol/K

R=1.99cal/mol/K

R=0.08206Latm/mol/K

Answer 2

Answer:

Which one of the following is not the value of R?

A1.99 cal K −1 mol −1

B0.0821 litre−atm K −1 mol −1

C9.8 kcal K −1 mol −1

D8.3 J K −1 mol −1

Explanation:

9.8 kcal K −1 mol −1 is not the value of R.

1.99 cal K −1 mol −1 is the value of R.
