t.boy007:
well,that's his own answer,any other answer contrary

mayorall: Nope..Chlorine is diatomic

t.boy007:
increase in pressure favours the forward reaction while reduction in pressure favours the backward reaction

t.boy007:
A
REASON:Rate of diffusion is inversely proportional to the relative molecular mass....i.e the more the relative molecula mass,the less its rate of diffusion...therefore from the question,argon has the highest RMM,it will definately have lesser rate of diffusion

t.boy007:
B
reason:the equation is exotermic.thus,increase in temperature favour the reverse reaction which is the reactant
