Question

le chateliers principle is a ______ that describes how a change in the system will direct the reaction as it re-establishes equilibrium.
a dynamic scale
b qualitative term
c quantitative measure
d objective comparision

Explanation:

Le Chatelier's principle is a qualitative term (or concept) that describes how a system at equilibrium responds to changes (like concentration, temperature, pressure changes) in a qualitative way (tells the direction of shift, not exact quantitative values). Option A (dynamic scale) is incorrect as it's not about a scale. Option C (quantitative measure) is wrong because the principle doesn't give quantitative measurements (like exact concentrations or amounts). Option D (objective comparison) is not relevant. So the correct option is B.

Answer:

B. qualitative term
