The correct answer is 0.04287 M
It is given that the rate constant of the reaction is 6.2 × 10⁻⁵ mol/L/s
Thus, as the rate of the reaction is in mol/L/s, it is a zero order reaction.
The initial concentration of a is 0.0500 M, and there is a need to find the concentration of a after 115 seconds. This can be done with the help of the equation:
[A]o -[A] = kt
[A] = [A]o - kt
= (0.0500 M) - (6.2 × 10⁻⁵) (115 s)
= 0.04287 M
