Chemical Reaction Engineering A reaction which is catalysed by an acid is also catalysed by any substance, which has a tendency to Gain a proton Lose an electron Lose a proton None of these Gain a proton Lose an electron Lose a proton None of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A chemical reaction is of zero order, when the reaction rate is (where, CA = concentration of reactant) ∝ CA None of these ∝ 1/CA Independent of temperature ∝ CA None of these ∝ 1/CA Independent of temperature ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Increased temperature reduces the activation energy Collision frequency increases Value of threshold energy decreases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Collision frequency increases Value of threshold energy decreases Fraction of molecules having threshold energy increases ANSWER DOWNLOAD EXAMIANS APP
