The degree of dissociation for a first-order reaction is not always equal to 1. The degree of dissociation is defined as the fraction of the reactant that has undergone dissociation or conversion to products. It is typically denoted by the symbol α.
For a first-order reaction, the rate of reaction is directly proportional to the concentration of the reactant. The expression for the rate of the reaction is given by:
rate = k[A]
where [A] is the concentration of the reactant and k is the rate constant.
The degree of dissociation (α) can be calculated using the equation:
α = (1 - e^(-kt))
where t is the reaction time.
If the reaction has reached completion (i.e., all of the reactant has been converted to products), then α will be equal to 1. However, if the reaction has not reached completion, α will be less than 1.
Therefore, the degree of dissociation for a first-order reaction is not always equal to 1. It depends on the specific conditions of the reaction and the reaction time.
