The apparent reaction order αi of reactant i was pointed out to be described as αi = ∂lnR/∂lnpi , where R is the reaction rate, and pi the partial pressure of reactant i. By substituting a fractional rate equation into this equation, apparent reaction orders could be correlated with parameters in the fractional rate equation, and a method of interconverting two types of rate expressions were proposed. A few examples of applications were shown
