Oil is hydrogenated using nickel catalyst in a __________ reactor. Slurry Batch Fluidised bed Fixed bed TRUE ANSWER : ? YOUR ANSWER : ?
For a heterogeneous catalytic reaction Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important The surface of the catalyst does not play an important role during reaction The catalyst does not form an intermediate complex with the reactant TRUE ANSWER : ? YOUR ANSWER : ?
With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be Data insufficient; can't be predicted Higher in P.F. reactor Same in both the reactors Higher in CSTR TRUE ANSWER : ? YOUR ANSWER : ?
Pick the WRONG design guideline for a reactor in which the reactions, A → R (desired) and A → S (undesired) are to take place. The ratio of the reaction rates is rR/rS = (k₁/k₂).Csub>Aa-b Use batch reactor or plug flow reactor, when a > b Use CSTR with a high conversion, when a > b Avoid recycle, when a > b Use high pressure and eliminate inerts, when a > b TRUE ANSWER : ? YOUR ANSWER : ?

In a continuous flow stirred tank reactor, the composition of the exit stream Is different than that in the reactor None of these Depends upon the flow rate of inlet stream Is same as that in the reactor TRUE ANSWER : ? YOUR ANSWER : ?
When the reaction occurs in the diffusion controlled region, the apparent activation energy as measured is only __________ the true value. Half Equal None of these Twice TRUE ANSWER : ? YOUR ANSWER : ?
In case of a __________ reactor, the composition in the reactor and at the exit of the reactor is the same. Back-mix Semi-batch Tubular Batch TRUE ANSWER : ? YOUR ANSWER : ?
If the time required to change the concentration of reactant to half its original value is independent of the initial concentration, the order of reaction is Zero One Two Three TRUE ANSWER : ? YOUR ANSWER : ?
