The Following Reaction Is First Order in a and First

question 75

Multiple Choice

The following reaction is first order in A and first order in B: A + B → Products Rate = k[A][B]
What is the rate constant k of this reaction in vessel (b) relative to the rate constant k of this reaction in vessel (a) ? Each vessel has the same volume.Shaded spheres represent A molecules,and unshaded spheres represent B molecules.

• A)rate constant k in vessel (b)/rate constant k in vessel (a)= 1:2
• B)rate constant k in vessel (b)/rate constant k in vessel (a)= 1:1
• C)rate constant k in vessel (b)/rate constant k in vessel (a)= 2:1
• D)rate constant k in vessel (b)/rate constant k in vessel (a)= 4:1
