Construction of the Rate-Conversion-Temperature Chart from Kinetic Data
Consider a first-order reversible exothermic reaction . This Demonstration represents the conversion versus temperature (the blue curve) for values of the reaction rate selected by the user. The orange curve corresponds to the equilibrium conversion (i.e., when the reaction rate equals zero). This equilibrium curve is typical of exothermic reversible reactions. Indeed the equilibrium conversion approaches zero and one at high and low temperatures, respectively.
Reaction rate is given by:
where is the conversion and .
The rate constants are given by:
and , (expressed in ).
