Chemical Reaction Engineering A chemical reaction is of zero order, when the reaction rate is (where, CA = concentration of reactant) None of these ∝ 1/CA ∝ CA Independent of temperature None of these ∝ 1/CA ∝ CA Independent of temperature ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is 0 2 1 3 0 2 1 3 ANSWER DOWNLOAD EXAMIANS APP
