Graph #C: Rate of reaction (maltose produced in 10 min.) verses amylopectin (substrate). Prepare a graph of the amount of maltose verses volume of amylopectin solution added.

Draw a smooth curve through the points.
Graph #D1: Rate of reaction (maltose produced in 10 min.) versus pH. Prepare a graph of the amount of maltose versus pH for samples D1, D2, and D3.

Draw a line from point to point.
