Chemical Reaction Engineering The dimensions of rate constant for reaction 3A → B are (l/gm mole)/min. Therefore the reaction order is 2 3 1 2 3 1 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering What is the order of a chemical reaction in which doubling the initial concentration of the reactants doubles the half life time of the reaction? 3 Zero 1 2 3 Zero 1 2 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Conversion increases with increase in temperature in case of a an __________ reaction. Autocatalytic Reversible exothermic Reversible endothermic Irreversible Autocatalytic Reversible exothermic Reversible endothermic Irreversible ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reaction A → B is conducted in an adiabatic plug flow reactor (PFR). Pure A at a concentration of 2 kmol/m³ is fed to the reactor at the rate of 0.01 m³ /s and at a temperature of 500 K. If the exit conversion is 20%, then the exit temperature (in k)is (Data: Heat of reaction at 298 K = - 50000 kJ/ kmole of A reacted Heat capacities CPA = CPB = 100kJ/kmole. K (may be assumed to be independent of temperature)) 600 400 500 1000 600 400 500 1000 ANSWER DOWNLOAD EXAMIANS APP
