Question

Rate of consumption of dinitrogenpentoxide is 0.5mol per litre per sec rate of formation of NO2 is ??

Answer 1

This might be the reaction you're referring to,

`N_2O_5 to 2NO_2 + O_2`

If that's the case, then the rates of disappearance or appearance are related by the stoichiometry of the reaction. Hence,

`0.5M*s^-1 * (2NO_2)/(N_2O_5) approx 1.0M*s^-1`

may be rate of appearance of nitrogen dioxide in this case.
