Answer:
(a) The rate of disappearance of is:
M/s
(b) The value of rate constant is: 0.83036
(c) The units of rate constant is:
(d) The rate will increase by a factor of 3.24
Explanation:
The rate of a reaction can be expressed in terms of the concentrations of the reactants and products in accordance with the balanced equation.
For the given reaction:
rate = =
=
-----(1)
According to the question, the reaction is second order in NO and first order in .
Then we can say that, rate = k -----(2)
where k is the rate constant.
The rate of disappearance of NO is given:
=
M/s.
(a) From (1), we can get the rate of disappearance of .
Rate of disappearance of =
= (0.5)*(
) M/s =
M/s.
(b) The rate of the reaction can be obtained from (1).
rate = = (0.5)*(
)
rate = M/s
The value of rate constant can be obtained by using (2).
rate constant = k =
k = = 0.83036
(c) The units of the rate constant can be obtained from (2).
k =
Substituting the units of rate as M/s and concentrations as M, we get:
=
(d) The reaction is second order in NO. Rate is proportional to square of the concentration of NO.
If the concentration of NO increases by a factor of 1.8, the rate will increase by a factor of = 3.24
