Comprehension Passage
In a general reaction A → B, the concentration of reactant A decreases over time as it is converted into product B. The plot of concentration of A versus time is shown in the graph. The shape of the graph reveals important information about the reaction order and the rate at which the concentration of A decreases.
From the graph, we observe a linear relationship between the concentration of A and time.
What is the relationship between the slope of the graph and the rate constant for a first-order reaction
1
The slope is equal to the rate constant.
2
The slope is inversely proportional to the rate constant.
3
The slope is equal to the square of the rate constant.
4
The slope is unrelated to the rate constant.
