Chemical Reaction Engineering In a zero order reaction, reactants concentration does not change with time and the Time for half change is half the time taken for completion of the reaction Reaction rate is trebled when the initial concentration is trebled Time for half change is independent of the initial concentration Time for completion of the reaction is independent of the initial concentration Time for half change is half the time taken for completion of the reaction Reaction rate is trebled when the initial concentration is trebled Time for half change is independent of the initial concentration Time for completion of the reaction is independent of the initial concentration ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For reactions in parallel viz A → P (desired product) and A → Q (unwanted product), if the order of the desired reaction is higher than that of the undesired reaction, a Single CSTR is the most suitable Both A and B Batch reactor is preferred over a single CSTR for high yield Tubular reactor is preferred over a single CSTR for high yield Single CSTR is the most suitable Both A and B Batch reactor is preferred over a single CSTR for high yield Tubular reactor is preferred over a single CSTR for high yield ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering 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 Higher in CSTR Same in both the reactors Higher in P.F. reactor Data insufficient; can't be predicted Higher in CSTR Same in both the reactors Higher in P.F. reactor Data insufficient; can't be predicted ANSWER DOWNLOAD EXAMIANS APP
