Q. No. 21- 40 carry 2 marks each
This section contains 10 multiple choice questions. Each question has four choices (A), (B), (C) and (D) out of which ONLY ONE is correct.
Q.
In the reaction,
P+Q →R+S
the time taken for 75% reaction of P is twice the time taken for 50% reaction of P. The concentration of Q
varies with reaction time as shown in the figure. The overall order of the reaction is
  • a)
    2
  • b)
    3
  • c)
    0
  • d)
    1
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
SECTION – 1Q. No. 21- 40 carry 2 marks eachThis section contains...
Overall order of reaction can be decided by the data given t75% = 2t50%
It is a first order reaction with respect to P.
From graph [Q] is linearly decreasing with time, i.e. order of reaction with respect to Q is zero and the rate
expression is r = k [P]1[Q]0.
Hence (D) is correct.
