The rate of reaction indicates the speed at which the reaction can occur. It can be expressed in terms of a change in the concentration of reactants or products per unit of time:
rate = concentration changetime change
The rate of reaction can be defined either as a decrease in the concentration of a reactant per unit of time or as an increase in the concentration of a product per unit of time.
Select the image to explore the activity that shows the different ways in which the rate of a reaction can be expressed.
When you click on the "Disappearance of reactants," "Appearance of products," or "Rate law expression" button, you will observe different expressions for the rate of the reaction.
Consider the following reaction:
2A+3Bรขยย3C+2D
Use the following data to determine the rate of reaction in terms of the disappearance of reactant A at time = 20 s.
| Time (s) | 0 | 20 | 40 |
| [A](M) | 0.1200 | 0.0720 | 0.0540 |
Express your answer in molar concentration per second to three significant figures.
Part B
