Reaction Rates

Explanation

A sequential first-order reaction with no back reaction is expressed by the equation

where k and k are the rate constants for the two-step reaction. The intermediate B is created and consumed during the overall reaction converting A to C.

The rate equations for this reaction are as follows.

To view the reaction rate curves for equations A( t) and B( t), we must first supply a starting value for the reactant, A ₀, as well as for the rate constants, k₁ and k₂. A third equation, Pr( t) is also generated from the difference between A( t) and B( t). Change the values above to see how the rate constants affect B and reaction time.
