Calculate the partial pressure of monatomic hydrogen in hydrogen gas at 2000 K and 1 atm pressure.

Given:
(i) For ½ H2 -> H, DeltaHo298=217,990 J; DeltaSo298=49.35 J/K.
(ii) Assume that the heat capacity of monatomic gas to be 3/2R
(iii)The heat capacity of H2 assume to be 31 J/(mol K)

Answer: PH = 5.22x10-4 atm
