Review Constants Periodic Tab Part A The gas-phase reaction of NO with F to form NOF and has an activation energy of E. = 6.30 kJ/mol and a frequency factor of A = 600-108 M. The reaction is believed to be bimolecular NO(s)+F2(g) NOF(g) + F(g) where NO is a free radical. Free radicals, species with an odd number of unbound electrons tend to be more reactive. This is one reason by NO reacts so readily with gases such as...

answer both parts A&B
A Review Constants Periodic Table Part A Phosgene (carbonyl chloride). COCI, 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) = COCI(g) Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 464 °C. At equilibrium, the concentrations were measured and the following results obtained: Gas Partial Pressure (atm) 0.780...
