The reaction between A and B is first order with respect to A and zero order with respect to B. Fill in the blanks in the following table:

Question 4.12: The reaction between A and B is first order with respect to A and zero order with respect to B.

 Fill in the blanks in the following table:
Answer
Given that
The order for the reactant A, x = 1
The Order for the reactant B, y = 0
Use the formula of rate
Rate = k [A]^x [B]^y
Plug the value of x and y we get
Rate = k [A]¹ [B]⁰ = k[A]
Plug the values from the first row of the given table, we get
2.0 × 10⁻² mol L⁻¹ min⁻¹ = k (0.1 mol L⁻¹)
k = 0.2 min⁻¹
Plug the values from the second row and use the value of k = 0.2 min⁻¹, we get
4.0 × 10⁻² mol L⁻¹ min⁻¹ = 0.2 min⁻¹ [A]
[A] = 0.2 mol L⁻¹
Plug the values from the third row and use the value of k = 0.2 min⁻¹, we get
Rate = 0.2 min⁻¹ × 0.4 mol L⁻¹ = 0.08 mol L⁻¹ min⁻¹
Plug the values from the fourth row and use the value of k = 0.2 min⁻¹, we get
2.0 × 10⁻² mol L⁻¹ min⁻¹ = 0.2 min⁻¹ [A]
[A] = 0.1 mol L⁻¹
