Interpretation:
The initial rate of formation of
Concept introduction:
Rate law: It is an equation that related to the
Rate: The rate is nothing but the change in concentration of substrate (reactant) or target (product) with time.
- The change in concentration term is divided by the respective
stoichiometric coefficient . - The negative sign indicates that substrates (reactants) concentration decrease as per the reaction progress.
- Rate of reaction is always represented by positive quantities.
(a)

Answer to Problem 13.126QP
The initial rate of formation of
Explanation of Solution
From the given information, the units of rate constant denotes a second-order reaction and the rate law is probably as follows
By using the ideal gas equation to solve for the initial concentrations of
The total pressure is 1658 mmHg and there are equimolar amounts of
Now, let’s convert the units of the rate constant to /M.min, and substitute the corresponding values in the rate law to solve the rate as follows.
We know that,

Answer to Problem 13.126QP
The rate formation of
Explanation of Solution
The integrated second-order rate law is used to calculate the concentration of
Similarly we can calculate the concentration of
Now,
We know that,
Therefore, the concentration of
