Calculate the percent yield for a reaction in which 0.38 g of NO2 reacts and 0.31 g of N2O5 is recovered when 2NO2 + O3 --> N2O5 + O2

Which statement is actually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.
