The rate law for the reaction A + B P is found to be rate = k[A]^2[B] . The rate constant of the reaction at 300 K is 6.0 M ⁻² s ⁻¹ . Calculate the rate of the reaction when [A] = 1 M and [B] = 0.2 M
Options
- A0.6 M s ⁻¹ .
- B1.2 M s ⁻¹ .
- C1.8 M s ⁻¹ .
- D2.4 M s ⁻¹ .
Correct answer
B. 1.2 M s ⁻¹ .
Step-by-step solution
Given rate law is Rate = k[A]^2[B] . Substituting the given values: Rate = 6.0 (1)^2 0.2 Rate = 1.2 M s ⁻¹ Answer: 1.2 M s ⁻¹ .
