The conversion is More when they are connected in series Less when they are connected in series Same whether they are connected in series or in parallel More when they are connected in parallel More when they are connected in series Less when they are connected in series Same whether they are connected in series or in parallel More when they are connected in parallel 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 3 1 0 2 3 1 ANSWER DOWNLOAD EXAMIANS APP
