The diagram above best illustrates the effect of decrease in
Answer Details
The diagram shows a decrease in the rate of reaction over time. The most likely explanation for this effect is a decrease in the concentration of the reactants. This is because a lower concentration means that there are fewer reactant molecules available to collide and react with each other, resulting in a slower rate of reaction.
Decreases in temperature, surface area, or pressure can also affect the rate of reaction, but these factors are not as clearly illustrated by the diagram. A decrease in temperature would cause the reaction to slow down, but the effect would be gradual rather than sudden. A decrease in surface area would also slow down the reaction, but it would not necessarily cause a sudden drop in the rate of reaction. A decrease in pressure might speed up the reaction if the reactants are in the gas phase, but again, the effect would not be as clearly illustrated by the diagram.
