If the energy balance in the chemical reaction within the thrust chamber is thought of as a two-step process, what is the initial step in the process?

If the energy balance in the chemical reaction within the thrust chamber is thought of as a two-step process, what is the initial step in the process? Correct Answer Isothermal chemical reaction at the reference temperature

The energy balance can be thought of as a two-step process. The first step involved in the isothermal chemical reaction of the propellants at the reference temperature. The second step involves the resultant gases having their temperature raised by the heat released from the previous chemical reaction.

Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
