Question
Given 2NOBr(g) -> NO(g)+Br2(l)
The reaction is second order and rate constant is 1.45 1/Ms at 20.0 degrees celcius. If the initial reactant concentration is 0.0480 M, calculate the reaction concentration after 10.0 seconds.
Expert Solution
Step 1
Given that,
A second-order reaction is 2NOBr(g) → NO(g) + Br2(l).
Also, the rate constant is k = 1.45 1/M.s at 20oC.
The initial consultation of the reactant is [A0] = 0.0480 M.
We have to calculate the concentration of the reactant, [A] after 10 sec.
So, the time is t = 10 sec.
Formula: The integrated rate law equation of the second-order reaction is
1/[A] = 1/[A0] + kt.
