A first order reaction has a rate constant of 0.0051 `min^(-1)`. If we begin with 0.10 M concentration of the reactant, What concentration of reactant will remain in solution after 3 hours?

Explanation

To solve the problem, we need to determine the concentration of a reactant after a certain period of time in a first-order reaction. Here are the step-by-step details of the solution:

### Step 1: Identify the given data
- Rate constant (k) = 0.0051 min^(-1)
- Initial concentration (A₀) = 0.10 M
- Time (t) = 3 hours = 3 × 60 minutes = 180 minutes

### Step 2: Use the first-order reaction formula
