Question

State true or false for the following problems and briefly explain why.

1.For an enzyme-catalyzed reaction with competitive inhibition, the maximum rate (Rmax) is less than Rmax in the absence of inhibition.

2. It is not possible to distinguish between chemisorption and physisorption by analyzing the Langmuir isotherm.

3. If B is a component of an ideal solution, B must be less than B*.

4. At constant T and P, Hmix must be negative for an ideal solution.

5. At constant T and P, Vmix must be positive for every solution.

6. In a real solution, the partial molar volume of a component can differ from the molar volume of the pure substance.

SOLUTION:

True or False?

a) For an enzyme-catalyzed reaction with competitive inhibition, the maximum rate (Rmax) is equal to Rmax in the absence of inhibition.

False

c) If B is a component of an ideal solution, B can be greater than B*.

Please provide notation of B*

d) At constant T and P, Gmix must be zero for an ideal solution.

True.

e) At constant T and P, Vmix must be positive for every solution.

False

f) In a real solution, the partial molar volume of a component can differ from the molar volume of the pure substance.

False, it is only true when partial molar volume is equal to molar volume.
