### Reaction Order DeterminationThe plots of \( \frac{1}{[A]} \) vs time, \( \ln([A]) \) vs time, and \([A]\) vs time for a solution of substance A are shown below. Determine the reaction order with respect to A.#### Graphs1. **First Graph** - X-axis: Time - Y-axis: \( \frac{1}{[A]} \) - Description: The graph shows a curved line decreasing towards the x-axis.2. **Second Graph** - X-axis: Time - Y-axis: \( \ln([A]) \) - Description: The graph displays a straight line with a negative slope, indicating a linear relationship between \(\ln([A])\) and time.3. **Third Graph** - X-axis: Time - Y-axis: \([A]\) - Description: The graph shows a linear decline with a slope equal to \(-k\), where \(k\) is the rate constant.#### Multiple Choice Options- second- zeroth- first (selected)The correct reaction order with respect to \(A\) is inferred from the third graph (\([A]\) vs time), showing a linear relationship. Hence, the reaction is **first order**.

The concentration versus time graph can be used to determine the order of the reaction. In the zero…
