[#376] The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the
Correct Answer
(B) Fraction of molecules having threshold energy increases
[#377] In a zero order reaction, reactants concentration does not change with time and the
Correct Answer
(A) Time for half change is half the time taken for completion of the reaction
[#378] A spherical porous catalyst particle of radius R is subjected to reactant A which reacts to form B by a zero order surface reaction A → B. Film mass transfer resistance is negligible and pore diffusion of A is rate controlling. The effectiveness factor of the catalyst is reported as $$frac{7}{8}$$. Which of the following statement is true?
Correct Answer
(A) Inner catalyst core of radius $$frac{{ ext{R}}}{8}$$ does not participate in reaction
[#379] For series reaction, the relative yield
Correct Answer
(D) Both A and C hold good
[#380] In a reversible reaction, a catalyst increases the rate of forward reaction
Correct Answer
(D) And the backward reaction equally
