STANDARD Chemistry Rate of Reaction MCQ Question
For a reaction, P + Q → 2R + S. Which of the following statements is incorrect?
Rate of disappearance of P = Rate of appearance of S
Rate of disappearance of Q = 2 × Rate of appearance of R
Rate of disappearance of P = Rate of disappearance of Q
Rate of disappearance of Q = 1/2 × Rate of appearance of R
Correct Answer
Detailed Explanation
The stoichiometry of the reaction indicates that the rate of disappearance of Q should be equal to the rate of appearance of R, not twice. Therefore, option B is incorrect.
