The reaction CO₂(g) + C(s) = 2 CO(g) has Kp = 5.78 at
1200 K.
a. Calculate the total pressure at equilibrium when 4.45 g of CO₂ is introduced into a 10.0-L container and heated to 1200 K in the presence of 2.00 g of graphite.
b. Repeat the calculation of part a in the presence of 0.50 g of graphite.
