PLEASE HELP The hydrogenation of unsaturated hydrocarbons is an important industrial process. Precious metals,

such as platinum and palladium, can greatly

increase the rate of this reaction. During this

process, the gaseous reactants are pumped

across a layer of metal powder. An example of this

process is shown below.

Describe how the metal probably increases the

reaction rate, identify whether this is an example

of homogeneous or heterogeneous catalysis, and

explain how you know.

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
