For a reaction A + B ® C + D has the following characteristics: If [A] remains the same, [B] is doubled, the rate of the reaction is doubled. If [B] stays the same and [A] doubles, the rate of the reaction stays the same. Both experiments were carried out at the same temperature, so the expression for the rate of the reaction is:

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
