Omg, lol. only answer if you know a hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as 1. heat 2. chemical energy 3. electrical energy. when used at home, a fuel cell eliminates the need for 1. oxygen 2. hydrogen 3. an electrical grid because the cell is portable.

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
