VELOCITY OF REACTIONS 39 value 188-4 as ordinate. The curves drawn are calculated by means of a formula given below. The rule of SCHUTZ is given by the tangent at the origin to the curve ; it is represented by a broken line and agrees with experiment till about 50 per cent are digested. … FIG. 8. As is seen from the diagram, the observed values indicated by circles lie below the theoretical curve represented by the formula on p. 42 (the line drawn) for high values of t and above it for low values of t. The explanation of this behaviour is obvious. It is supposed that every molecule…
