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 + 1 T ∝ an T ∝ 1/an T ∝ 1/an - 1 T ∝ 1/an + 1 T ∝ an T ∝ 1/an ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate constant 'k' and absolute temperature 'T' are related by collision theory (for bimolecular) as k ∝ exp(-E/RT) k ∝ T k ∝ T1.5 k ∝ √T k ∝ exp(-E/RT) k ∝ T k ∝ T1.5 k ∝ √T ANSWER DOWNLOAD EXAMIANS APP
