To draw the graph of the rate of reaction against temperature:

Set up the axes.
- Draw a horizontal axis (x-axis) and label it "Temperature (°C)".
- Draw a vertical axis (y-axis) and label it "Rate of reaction".
Choose appropriate scales.
- For the x-axis (Temperature), a suitable scale would be $1 \text{ cm}$ representing $5^\circ\text{C}$ , starting from $0^\circ\text{C}$ and going up to at least $50^\circ\text{C}$ .
- For the y-axis (Rate of reaction), a suitable scale would be $1 \text{ cm}$ representing 0.5 units of rate, starting from 0 and going up to at least 5.0 units.
Plot the data points.
- For each pair of (Temperature, Rate of reaction) from the table, mark a point on your graph.
  
  $(5, 0.3)$
  
  $(10, 0.5)$
  
  $(20, 1.25)$
  
  $(25, 2.0)$
  
  $(30, 3.5)$
  
  $(35, 4.8)$
  
  $(38, 4.8)$
  
  $(45, 2.5)$
  
  $(50, 0.8)$
Draw a smooth curve.
- Connect the plotted points with a smooth curve. Do not use straight lines between points. The curve should show an initial increase, reach a peak, and then decrease.
The graph should look like a bell-shaped curve, rising from 0.3 at $5^\circ\text{C}$ to a maximum rate of 4.8 between $35^\circ\text{C}$ and $38^\circ\text{C}$ , and then falling to 0.8 at $50^\circ\text{C}$ . This shape indicates the optimum temperature for salivary amylase.
