For the reaction, 2 ~A + B 3 C + D , which of the following does not express the reaction rate?
Options
- A- d[ ~A ] d t
- B- d[ C ] 3 d t
- C- d[ ~B ] d t
- Dd[ D ] d t
Correct answer
B. - d[ C ] 3 d t
Step-by-step solution
For the reaction 2 ~A + B 3 C + D . The reaction rate is written as follows: The reaction rate w.r.t. A =- 1 2 d[ ~A ] d t The reaction rate w.r.t. B =- d[ ~B ] d t The reaction rate w.r.t. C =+ 1 3 d[ C ] d t The reaction rate w.r.t. D =+ d[ D ] d t Related Theory During the course of the reaction shown below, reactants A and B are consumed while the concentration of product A B increases. The reaction rate can be determined by measuring how fast the concentration of A or B decreases, or by how fast the concentrat
