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 does the negative slope of the curve in the plot indicate
1
The concentration of A increases with time.
2
The concentration of A decreases with time.
3
The concentration of A remains constant.
4
The concentration of B increases with time.
