Find K_c for the reaction:

1) PCl₅(g) → ← PCl₃(g) + Cl₂(g)

At 250 °C the reaction is initiated with 1.00 atm of PCl₅. At equilibrium the partial pressure of PCl₅ is reduced to 0.30 atm.

2) COCl₂(g) → ← CO(g) + Cl₂(g)

At 527 °C the reaction is initiated with 1.00 atm of COCl₂. At equilibrium the partial pressure of COCl₂ is reduced to 0.42 atm.

If the last digit of your student ID number is odd, answer question 1; if the last digit of your student ID number is even, answer question 2.

Turn in the following on a clean, full sheet of paper (not torn out of a notebook):
