Question

Difference between universal gas constant and gas constant

Answer 1

Explanation:

Then it is called a characteristic gas constant. The key difference between universal gas constant and characteristic gas constant is that universal gas constant is only applicable for ideal gases whereas characteristic gas constant is applicable for real gases. ... The volume of those gas molecules is negligible.

Answer 2

Answer:

The characteristic gas constant is the value of R for a specific gas for use in the equation P = RT. It is equal to the universal gas constant divided by the molar mass of the particular gas. If you are working at human scales, then use the universal gas constant.
