Chemical Reaction Engineering Find a mechanism that is consistent with the rate equation and reaction given below: 2A + B → A₂B, ( - rA) = k.CA.CB A + B ⇋ AB ; AB + A → A₂B A + A ⇋ AA;AA + B → A₂B A + A ⇋ AA;AA + B → A₂B A + B ⇋ AB;AB + A → A₂B A + B ⇋ AB ; AB + A → A₂B A + A ⇋ AA;AA + B → A₂B A + A ⇋ AA;AA + B → A₂B A + B ⇋ AB;AB + A → A₂B 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 1 2 3 0 1 2 3 ANSWER DOWNLOAD EXAMIANS APP
