Examine each graph carefully. Each graph represents the progress of a reaction over time, with the y-axis likely representing concentration or rate and the x-axis representing time.
Identify the key features of each graph. Look for the peak of each curve, which indicates the maximum rate of reaction, and the slope of the curve, which indicates how quickly the reaction proceeds.
Compare the slopes of the descending parts of the curves. A steeper slope indicates a faster reaction, while a gentler slope indicates a slower reaction.
Determine which graph has the gentlest slope after the peak. This graph represents the reaction that proceeds the slowest.
Based on the analysis, identify which reaction corresponds to the graph with the gentlest slope. This will be the reaction that proceeds the slowest.
