When liquid hydrogen peroxide is mixed with liquid hydrazine a very fast exothermic reaction takes place which can propel a rocket. the reaction products are nitrogen and steam. (a) suggest why the reaction needs to be fast
(b) If the rocket is loaded with 680 kg of hydrogen peroxide, calculate the mass of hydrazine which will be needed to react with.

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
