In gaseous reactions, what happens if there is an increase in pressure?
Equilibrium shifts to side with fewer moles of gas
For a reaction that produces more moles of gas, what happens if the pressure is increased?
Equilibrium shifts to side with more moles of gas
What happens to the yield of an endothermic reaction if the temperature is decreased?
Increases yield of reaction
When pressure decreases in a gaseous reaction, where does the equilibrium shift?
To the side with fewer moles of gas
If a reaction produces fewer moles of gas, what happens when pressure is increased?
Equilibrium shifts to side with fewer moles of gas
In which direction does the equilibrium shift if a reaction produces more moles of gas and pressure is increased?
Right, side with fewer moles of gas
In a closed system, when does equilibrium occur for a reversible reaction?
When the reactions occur at exactly the same rate in each direction
What happens when a reversible reaction reaches equilibrium in a closed system?
The rate of forward reaction equals the rate of reverse reaction
How do changing conditions affect the relative amounts of reacting substances at equilibrium?
They determine the amounts of reactants and products at equilibrium
If a reversible reaction is exothermic, what happens at equilibrium if the temperature is increased?
The equilibrium shifts to the right to favor the endothermic reaction
What is the impact on equilibrium when a reversible reaction takes place in an open system?
The system will not reach equilibrium as reactants escape
What happens to the position of equilibrium when the concentration of reactants is increased?
Shifts towards products
How does increasing the concentration of products affect the position of equilibrium?
Shifts towards reactants
If a reaction is endothermic and the temperature is increased, what is the effect on equilibrium?
Shifts towards products
In Le Chatelier's principle, what does the system do when a change is made to any of the conditions of equilibrium?
Adapts to maintain the change
For an exothermic reaction, what happens if the temperature is decreased?
Shifts towards reactants
When a system is no longer at equilibrium due to a change in concentration, what occurs until equilibrium is reached again?
All substances' concentrations change
In a gaseous reaction that produces the least number of molecules, what happens to the equilibrium if the pressure is increased?
Equilibrium shifts to the right side of the equation
For a reaction producing a larger volume of gas (more moles), what happens if the pressure is decreased?
Equilibrium shifts to the left side of the equation
How does a decrease in temperature affect the yield of an endothermic reaction?
Increases yield of reaction
When a decrease in pressure occurs in a gaseous reaction, where does the equilibrium shift?
To the side with fewer moles of gas
If a reaction produces fewer moles of gas, what happens when the pressure is increased?
Equilibrium shifts to the right side of the equation
What is the effect of pressure changes on equilibrium in gaseous reactions?
Pressure affects equilibrium based on moles of gas produced
What symbol is typically used to represent a reversible reaction?
⇌
How can the direction of a reversible reaction be altered?
By changing the conditions, such as using hot conditions for the forward reaction
In which type of reactions can the products react to form the original reactants?
Reversible reactions
If a reversible reaction is endothermic in one direction, what is it in the opposite direction?
Exothermic
What type of change occurs if a reversible reaction is endothermic one way?
It is exothermic in the opposite direction
What is the relationship between an endothermic reaction and an exothermic reaction in a reversible reaction?
One is endothermic, and the other is exothermic
Learn about Le Chatelier's principle, which states that a system at equilibrium will respond to counteract changes made to any of the conditions. Understand how changing the concentration of reactants or products shifts the equilibrium position.
