Question: The experimental data for the reaction, 2A + B<sub>2</sub>® 2AB, is Expt. [A] [B<sub>2</sub>] Rate...
The experimental data for the reaction,
2A + B2® 2AB, is
Expt. [A] [B2] Rate (s–1)
No.
1. 0.50 0.50 1.6×10–4
2. 0.50 1.00 3.2× 10–4
3. 1.0 1.00 3.2×10–4
The rate equation for the above data is -
A
Rate = k[B2]2
B
Rate = k[B2]
C
Rate = k[A]2[B]2
D
Rate = k[A]2 [B]
Answer
Rate = kB<sub>2</sub>
Explanation
Solution
r = k [A]x [B]y
1.6 × 10–4 = k [0.5]x [0.5]y …… (1)
3.2 × 10–4 = k [0.5]x [1.0]y …… (2)
3.2 × 10–4 = k [1.0]x [1.0]y …… (3)
(2) ø (1) 2 = 2y Ž y = 1
(3) ø (2) 1 = 2x Ž x = 0
r = k [A]° [B]1
