A) \[{{C}_{P}}\] of hydrogen gas is \[\frac{5}{2}R\]
B) \[{{C}_{V}}\] of hydrogen gas is \[\frac{7}{2}R\]
C) \[{{H}_{2}}\] has very small values of \[{{C}_{p}}\] and \[{{C}_{V}}\]
D) \[{{C}_{p}}-{{C}_{V}}~=1.99cal/mole-K\] for \[{{H}_{2}}\]
Correct Answer: D
Solution :
[d] For any gas \[{{C}_{P}}-{{C}_{V}}=1.99\approx 2\frac{cal}{mol\text{-}K}\]
