The rate constant for a certain reaction is k = 5.50×10−3 s−1 . if the initial reactant concentration was 0.550 m, what will the concentration be after 2.00 minutes? express your answer with the a

0.19 m

Explanation:- Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

   (1)

k= rate constant

x= order= 1

As the units of , the reaction follows first order kinetics.

Also rate is the change in concentration of reactants or products in a given time.

       (2)

Equating (1) and (2)

terd muffin is the correct answer

more than, less

less than, more
