Question
The bromination of acetone that occurs in acid solution is represented by
CH3COCH3 (aq) + Br2 (aq) → CH3COCH2 Br (aq) + HBr (aq)
Given :
Based on the above data, rate law is :
CH3COCH3 (aq) + Br2 (aq) → CH3COCH2 Br (aq) + HBr (aq)
Given :
Based on the above data, rate law is :
Options
A.
= k [CH3COCH3] [Br2] [H+]
= k [CH3COCH3] [Br2] [H+]B.= k [CH3COCH3] [H+]
= k [CH3COCH3] [H+]C.= k [CH3COCH3] [Br2]
= k [CH3COCH3] [Br2] D.= k [CH3COCH3] [Br2] [H+]2
= k [CH3COCH3] [Br2] [H+]2Solution
According to above data.
suppose rate law,
= k [CH3COCH3]a [Br2]b [H+]c
by data (i) and (ii) conc. of [Br2] increased 2 times and conc. of [CH3COCH3] and [H+] constant rate remains same. Then zero order wrt Br2.
Similarly conc. of [H+] increased 2 times rate increased 2 times, so first order wrt H+.
Similarly 1st order wrt CH3COCH3
Then,
= k [CH3COCH3] [H+]
suppose rate law,
= k [CH3COCH3]a [Br2]b [H+]cby data (i) and (ii) conc. of [Br2] increased 2 times and conc. of [CH3COCH3] and [H+] constant rate remains same. Then zero order wrt Br2.
Similarly conc. of [H+] increased 2 times rate increased 2 times, so first order wrt H+.
Similarly 1st order wrt CH3COCH3
Then,
= k [CH3COCH3] [H+]Create a free account to view solution
