The energy equation then would be
v
(16.248)
with
=∆
r
(16.249)
where
C
v
is the (constant) specic heat at constant volume
T is the absolute temperature
q is the heat released from the reaction
is the heat of reaction of the complete reaction
In this equation, λ is a parameter that varies from 0 to 1 indicating the degree of reaction:
λ = 0 means the reaction has not even begun
λ = 1 means the reaction is complete
In this simplest model, there are only two states, 0 and 1.
We can rearrange Equation 16.247 as follows:
T
=
(16.250)
If we recall the relationship between specic heat a
