Given a second-order reaction with a rate constant \(k = 0.1 \, \text{M}^{-1}\text{s}^{-1}\) and an initial concentration \([R]_0 = 0.5 \, \text{M}\), calculate the time it takes for the concentration of the reactant to decrease to \(0.25 \, \text{M}\). What is the half-life of this reaction? How does this compare to a... | Okay, so I need to solve this problem about a second-order reaction. Let me start by recalling what I know about reaction kinetics.
First, the problem states that it's a second-order reaction with a rate constant \(k = 0.1 \, \text{M}^{-1}\text{s}^{-1}\) and an initial concentration \([R]_0 = 0.5 \, \text{M}\). They ... | To solve the problem, we start with the integrated rate law for a second-order reaction:
\[
\frac{1}{[R]} = kt + \frac{1}{[R]_0}
\]
Given:
- \(k = 0.1 \, \text{M}^{-1}\text{s}^{-1}\)
- \([R]_0 = 0.5 \, \text{M}\)
- \([R] = 0.25 \, \text{M}\)
Plugging in the values:
\[
\frac{1}{0.25} = 0.1t + \frac{1}{0.5}
\]
