According to the theoretical bases of thermokinetics and analog thermo
gram method, a general analog thermogram method for several types of r
eversible reactions, with which the rate constants of forward and back
ward reactions and equilibrium constant can be calculted from the same
thermogram simultaneously, has been proposed in this paper. The therm
okinetics of the reactions of nitroethane with ammonia at 15 degrees C
and 25 degrees C and with tris (hydroxymethyl)aminomethane at 15 degr
ees C and 30 degrees C have been studied with this method, respectivel
y. The results of rate constants and equilibrium constants calculated
with this method are in agreement with those in literatures. Therefore
, the analog thermogram method for the reversible reactions is believe
d to be correct.
