Understanding Chemical Equilibrium Concepts

Front

This endothermic reaction is at equilibrium. If its temperature is increased (at constant volume and pressure), which way will the equilibrium shift?

Back

To products (right)

Front

How could we make this reaction happen more quickly?

Back

Crush the chalk to increase the surface area.

Front

At what time does the reaction reach equilibrium? Options: t₁, t₂, t₃, t₄

Back

t₂

Front

According to Le Chatelier's Principle, what happens to the position of equilibrium when the concentration of a reactant is increased?

Back

The equilibrium shifts to the right.

Front

Which factor does NOT affect the position of equilibrium in a chemical reaction? Options: Temperature, Pressure, Catalyst, Concentration

Back

Front

In a closed system, if the volume is decreased, what happens to the equilibrium position of a gaseous reaction?

Back

The equilibrium shifts towards the side with fewer moles of gas.

Front

Which of the following statements is true regarding the effect of a catalyst on a chemical equilibrium?

Back

A catalyst increases the rate of both the forward and reverse reactions equally.
