Kinetics Comparison  

Students build a model of a zero, then first and finally second order reaction. The model shown here combines the three. Students can then compare the effects on the graph.

STELLATM software is needed to view the model in Mac (hqx) format or PC format.

First_A(t) = First_A(t - dt) + (- Rate_decompose_first_A) * dt
INIT First_A = 5

OUTFLOWS:
Rate_decompose_first_A = First_A*Rate_constant
Second_A(t) = Second_A(t - dt) + (- Rate_decompose_second_A) * dt
INIT Second_A = 5

OUTFLOWS:
Rate_decompose_second_A = Rate_constant*Second_A^2
Zero_A(t) = Zero_A(t - dt) + (- Rate_decompose_zero_A) * dt
INIT Zero_A = 5

OUTFLOWS:
Rate_decompose_zero_A = Rate_constant
Rate_constant = 0.1
