Chemical Reaction Engineering Which of the following does not produce a change in the value of rate constant of a reaction? None of these Concentration and catalyst Pressure Temperature None of these Concentration and catalyst Pressure 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 2 3 0 1 2 3 0 1 ANSWER DOWNLOAD EXAMIANS APP
