Chemical Reaction Engineering In a zero order reaction, reactants concentration does not change with time and the Time for half change is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled Time for half change is half the time taken for completion of the reaction Time for completion of the reaction is independent of the initial concentration Time for half change is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled Time for half change is half the time taken for completion of the reaction Time for completion of the reaction is independent of the initial concentration 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 1 3 0 2 1 3 0 2 ANSWER DOWNLOAD EXAMIANS APP
