Question

Which of the following choices match(es) with hydrogen gas at $$200\ atm$$ and $$273\ K$$?

Answer 1

Correct option is D. $$P(V-nb)=nRT$$
Hydrogen at high pressure behaves as real gas i.e $$\mathrm{Z \displaystyle \neq 1 }$$.

At high pressure, molecules come close to each other. So, repulsive forces dominate.

The Real Gas Equation at high pressure becomes : $$\mathrm{p(V-nb) = nRT}$$

Hence, Option "A" & "D" are the correct answers.
