Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Collision frequency increases Fraction of molecules having threshold energy increases Value of threshold energy decreases Increased temperature reduces the activation energy Collision frequency increases Fraction of molecules having threshold energy increases Value of threshold energy decreases Increased temperature reduces the activation energy ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The increase in the rate of reaction with temperature is due to Increase in the average kinetic energy of the reacting molecules Decrease in activation energy None of these Increase in the number of effective collisions Increase in the average kinetic energy of the reacting molecules Decrease in activation energy None of these Increase in the number of effective collisions ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A batch adiabatic reactor at an initial temperature of 373°K is being used for the reaction, A → B. Assume the heat of reaction is - 1kJ/mole at 373°K and heat capacity of both A and B to be constant and equal to 50J/mole.K. The temperature rise after a conversion of 0.5 will be 20°C 100°C 10°C 5°C 20°C 100°C 10°C 5°C ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Enzymes (a protein) are catalysts found in organisms. Its efficiency of catalysing a reaction is due to its capacity to lower the activation energy of the reaction.
