1.	If a reaction is of third order then what will happen if its reactant concentration is doubled
Answer» double the concentrationof reactant X and the RATE increases by 2a, then the orderof reactant X is "a". ... For example, if you have a REACTIONWITH one reactant, A, and youdouble [A] and the rate DOUBLES,then the rate=k[A]1.
