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 ∝ an T ∝ 1/an + 1 T ∝ 1/an T ∝ 1/an - 1 T ∝ an T ∝ 1/an + 1 T ∝ 1/an T ∝ 1/an - 1 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering At a given value of E/R (ratio of activation energy and gas constant), the ratio of the rate constants at 500°K and 400°K is 2, if Arrhenious law is used. What will be this ratio, if transition state theory is used with the same value of E/R? 2.24 2 1.6 2.5 2.24 2 1.6 2.5 ANSWER DOWNLOAD EXAMIANS APP
