SATHEE: Chemical Kinetics Question 315

Chemical Kinetics Question 315

Question: For the reaction, $3 A + 2 B \to C + D$ , the differential rate law can be written as:

Options:

A) $\frac{1}{3} \frac{d [A]}{d t} = \frac{d [C]}{d t} = k {[A]}^{n} {[B]}^{m}$

B) $- \frac{d [A]}{d t} = \frac{d [C]}{d t} = k {[A]}^{n} {[B]}^{m}$

C) $+ \frac{1}{3} \frac{d [A]}{d t} = - \frac{d [C]}{d t} = k {[A]}^{n} {[B]}^{m}$

D) $- \frac{1}{3} \frac{d [A]}{d t} = \frac{d [C]}{d t} = k {[A]}^{n} {[B]}^{m}$

Show Answer

Answer:

Correct Answer: D

Solution:

[d] For the reaction $3 A + 2 B \overset{}{\to} C + D$ Rate of disappearance of A = Rate of appearance of C reaction $= - \frac{1}{3} \frac{d [A]}{d t} = \frac{d [C]}{d t} = k {[A]}^{n} {[B]}^{m}$
