Paragraph: The following reaction was studied at 25^ C in benzene solution containing 0.1 M pyridine. (A) CH ₃ OH + ( C ₆ H ₅ )₃ CCl ( C ₆ H ₅ )₃ COCH ₃ + HCl The following sets of data were observed. Question: Rates d [ C ] dt in sets (I), II and III are respectively (in M min ⁻¹ ) Rate constant of the above experiment is (in L ^2 ~m ⁻² ~min ⁻¹ )

Options

  1. AK[A][B]
  2. BK [ A ]^2[ ~B ]
  3. CK [ A ][ B ]^2
  4. DK[A]^2[B]^4

Correct answer

B. K [ A ]^2[ ~B ]

Step-by-step solution

d x d t =K[A]^2[B] K = ( dx / dt ) [ A ]^2[ ~B ] =0.26
