Chemical Reaction Engineering 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 Avoid recycle, when a > b Use high pressure and eliminate inerts, when a > 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 Use batch reactor or plug flow reactor, when a > b Use CSTR with a high conversion, when a > b ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The rate of the chemical reaction A → B doubles as the concentration of A i.e.., CA is doubled. If rate of reaction is proportional to CAn, then what is the value of n for this reaction? 0.5 2 1 0.5 2 1 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering 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 Three One Two Zero Three One Two Zero ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A first order gaseous phase reaction is catalysed by a non-porous solid. The kinetic rate constant and the external mass transfer co-efficients are k and kg respectively. The effective rate constant (keff) is given by 1/keff = 1/k + 1/kg keff = (k+ kg)/2 keff = (kkg)1/2 keff = k + kg 1/keff = 1/k + 1/kg keff = (k+ kg)/2 keff = (kkg)1/2 keff = k + kg ANSWER DOWNLOAD EXAMIANS APP
