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 (R_max) is less than R_max 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, μ_B must be less than μ_B^*.

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

5. At constant T and P, ΔV_mix 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.

Answer 1

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, μB can be greater than μB*.

Please provide notation of μB*

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

True.

e) At constant T and P, ΔVmix 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.
