To draw the graph of the rate of reaction against temperature: Step 1: 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". Step 2: Choose appropriate scales. For the x-axis (Temperature), a suitable scale would be 1 cm representing 5^, starting from 0^ and going up to at least 50^. For the y-axis (Rate of reaction), a suitable scale would be 1 cm representing 0.5 units of rate, starting from 0 and going up to at least 5.0 units. Step 3: 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) Step 4: 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^ to a maximum rate of 4.8 between 35^ and 38^, and then falling to 0.8 at 50^. This shape indicates the optimum temperature for salivary amylase. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
