5. (20%) The two gases H₂(g) and D₂(g) (Deuterium molecule) are mixed in equal molar amounts. The mixture tends to react to form HD(g) (g) according to the isotope exchange reaction H₂(g) + D₂(g)⇌2HOD(g).

(i) (2%) Initial partial pressures (before reaction) are 1.00 atm, and 1.00 atm for H₂(g) and D₂(g), respectively. What is the partial
pressure of each gas at equilibrium?
