question 38

Multiple Choice

• B) the pattern increases in size. (central maximum wider; other maxima farther from it)
• C) it does not affect the size of the pattern.
• D) the width of the central maximum increases, but the other maxima do not change in position or width.
• E) the width of the central maximum decreases, but the other maxima do not change in position or width.

Definitions:

Dynamic Equilibrium

A state of balance in a system where opposing processes occur at equal rates, maintaining a constant condition.

Reverse Reaction

A reverse reaction is a chemical reaction that occurs in the opposite direction of the forward reaction, resulting in the conversion of the reaction products back into the original reactants.

Forward Reaction

A chemical reaction that proceeds in the direction of forming products from reactants, as initially written in a chemical equation.

Dynamic Equilibrium

A situation in which two opposing processes occur at the same rate, leading to no net change in the system.
