It signifies that __________ in the two reactors. Conversion in both will be the same but concentrations will be different Both conversion as well as concentration are same Both the conversion as well as concentrations will be different None of these Conversion in both will be the same but concentrations will be different Both conversion as well as concentration are same Both the conversion as well as concentrations will be different None of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Organic catalysts differ from the inorganic catalyst in the sense that the former is Prohibitively costly Active at very high temperature only Active at cryogenic temperatures only Proteinous in nature Prohibitively costly Active at very high temperature only Active at cryogenic temperatures only Proteinous in nature 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 1 0 2 3 1 0 ANSWER DOWNLOAD EXAMIANS APP
