Chemical Reaction Engineering If n = overall order of a chemical reaction. a = initial concentration of reactant. t = time required to complete a definite fraction of the reaction. Then pick out the correct relationship. T ∝ 1/an - 1 T ∝ 1/an T ∝ 1/an + 1 T ∝ an T ∝ 1/an - 1 T ∝ 1/an T ∝ 1/an + 1 T ∝ an ANSWER DOWNLOAD EXAMIANS APP
