Physical Pharmaceutics 2 MCQs: 254 Questions & Answers in Faculty

In the degradation studies of aspirin suspension, the orders observed initially and at the end, respectively, are: -

In the hydrolysis of sucrose in hydrochloric acid solution, the change in the optical rotation follows the order:

The conversion of trans-stilbene to cis-stilbene follows the molecularity:

In the study of the rate of a reaction, 100 ml of 0.1 N hydrochloric acid is added to 10 ml methyl acetate for the reaction to occur. The reason for making such a proportion is to make:

A second order reaction follows pseudo-first order reaction, when the concentrations of:

The reaction rate constant (k) is 2.0 x 10-3 min.-1 for aspirin hydrolysis in 0.1 N hydrochloric acid at 1mg/ml concentration. Under same conditions, if the product contains aspirin 4 mg/ml of the initial concentration, the k value in minutes-1 will be:

The solid state decomposition of aspirin in presence of moisture follows the order:

When a series of steps are involved in a reaction, the ‘overall rate’ of a reaction depends upon the rate(s) of:

The integral equation (in common notation) k = x/at (a - x) is concerned with the order:

The integral rate equation for a reaction (in common notation) is written as log C = log Co - (kt/2.303). When a graph is drawn log c vs. t, the slope will be:
