Question
The following reaction is second-order in $\mathrm{A}$ and first-order in $\mathrm{B}$.$\mathrm{A}+\mathrm{B} \longrightarrow$ products(a) Write the rate expression.(b) Consider the following one-liter vessel in which each square represents a mole of $\mathrm{A}$ and each circle represents a mole of $\mathrm{B}$.What is the rate of the reaction in terms of $k ?$(c) Assuming the same rate and $k$ as (b), fill the similar one-liter vessel shown in the figure with an appropriate number of circles (representing B).
Step 1
Therefore, the rate expression can be written as follows: \[Rate = k[A]^2[B]\] where k is the rate constant, [A] is the concentration of A, and [B] is the concentration of B. Show more…

The following reaction is second order in A and first order in B: A + B → Products Rate = k[A]²[B] What is the initial rate of this reaction in vessel (b) relative to the initial rate of this reaction in vessel (a)? Each vessel has the same volume. Shaded spheres represent A molecules, and unshaded spheres represent B molecules present at the beginning of the reaction. rate in vessel (b)/rate in vessel (a) = 1:2 rate in vessel (b)/rate in vessel (a) = 1:1 rate in vessel (b)/rate in vessel (a) = 2:1 rate in vessel (b)/rate in vessel (a) = 4:1
14. Study the chemical reaction. A + B ⟶ C + D A scientist studying this reaction states that the reaction is first order with regard to A and zeroth order with regard to B. What is the rate law for this reaction? a. Rate = K [A][B] b. Rate = K [B] c. Rate = K [A]^2[B] d. Rate = K [A]
For the reaction $\mathrm{A} \longrightarrow$ products The following data are obtained. (a) Determine the order of the reaction. (b) Write the rate expression for the reaction. (c) Calculate $k$ for the experiment above.
