Question

true/false?

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

b) the Langmuir isotherms for chemisorption and physisorption are identical.

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

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

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

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

(a) True - there is nothing to inhibit the rate

(b) False - Langmuir adsorption isotherm assumes only mono layer on adsorbent which best fit for chemisorption

(d) False - it need not to be zero

(e) False - may also negative

(f) Yes - depending upon the interaction of components in the mixture
