Which of the following graphs most appropriately represents a zero-order reaction?
- A
Reactant concentration plotted against time as a horizontal straight line (concentration constant).
- B
Reactant concentration plotted against time as a straight line of negative slope (concentration falling linearly).
- C
Reactant concentration plotted against time as a curve falling steeply and then flattening (exponential decay).
- D
Rate plotted against time as a straight line of negative slope.
