What will happen to the reaction mixture at equilibrium if the temperature is decreased?
If the temperature of a reaction mixture at equilibrium is decreased, the system will respond by favoring the exothermic direction of the reaction to produce heat. According to Le Chatelier's principle, this shift will result in an increase in the concentration of products if the forward reaction is exothermic, or an increase in reactants if the reverse reaction is exothermic. The overall effect will be a change in the equilibrium position to counteract the decrease in temperature.

What will happen to the mixture at equilibrium if the temperature is decreased?
The system will rebalance.
To maximize equilibrium yield of methanol would you use high or low temperature?
High because a higher pressure is the result of decreased volume and when a decreased volume for the equilibrium mixture is involved, the shift is toward the side with the least amount of mols of gas. 3 for reactants and 1 for methanol so towards methanol
Why the reaction mixture does not have 50 percent reactants and 50 percent products at equilibrium position?
At equilibrium, the reaction mixture does not have 50 percent reactants and 50 percent products because the reaction has reached a dynamic state where the rates of the forward and reverse reactions are equal. This means that both reactants and products are continuously being formed and consumed at the same rate, leading to a constant concentration of reactants and products. The specific ratio of reactants to products at equilibrium is determined by the equilibrium constant for the reaction, which is unique to each reaction and depends on factors such as temperature and pressure.
What will happen to the reaction mixture at equilibruim if the volume of the container is increased?
The equilibrium will be re-established.
Why the reaction mixture does not have 50 percent reactant and 50 percent product at equilibrium position?
The ratio of product to reactant is dependant on many different things, from the reactants and products themselves to the pressure, temperature and other parameters of the reaction conditions such as the presence of a catalyst. Some reactions are product favoured by nature and at room temperature and 100kPa will always lie at the product side of the equilibrium at STP. Others, like the Haber Process, are reactant favoured and, without manipulation, will produce very little product. To maximise the product it must be made thermodynamically and entropically favourable for it to do so.

What does equilibrium and equilibrium mixture mean?
A quantity that characterizes the position of equilibrium for a reversible reaction; its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.

How do solids affect equilibrium in a chemical reaction?
Solids do not affect the equilibrium of a chemical reaction because their concentration remains constant and does not change during the reaction. Only the concentrations of gases and dissolved substances in a reaction mixture can affect the equilibrium position.

The equilibrium will be re-established.
When you mixed room temperature salt and room temperature water the mixture changes temperature. If you leave this mixture undisturbed for several hours what would happen to the temperature?
The temperature of the mixture would eventually reach equilibrium with the surrounding room temperature as the system stabilizes. This process is known as thermal equilibrium where the heat is evenly distributed throughout the system.
How does temperature affect Keq of a reaction?
Changing the temperature will change Keq - apex (Explanation): Keq is closely related to temperature and is part of the equation, so changing temperature will change Keq. Temperature does speed up the reaction sometimes, but that is not the only thing that it can affect.
What indicates a small equilibrium constant?
A small equilibrium constant (Kc) typically indicates that the reaction tends to favor the reactants at equilibrium rather than the products. This suggests that the reaction is not proceeding to a significant extent in the forward direction.

What is the concentration of HF in an equilibrium mixture established by adding mol each of H2 and F2 to a 1.00 L container at this temperature?
To determine the concentration of HF in an equilibrium mixture established by adding 1 mol each of H2 and F2 to a 1.00 L container, we first recognize that the reaction is (H_2 + F_2 \rightleftharpoons 2HF). Assuming the reaction goes to completion, we would initially have 1 mol of H2 and 1 mol of F2, which would produce 2 mol of HF. Since the total volume is 1.00 L, the concentration of HF at equilibrium would be 2 M. However, the actual equilibrium concentrations depend on the equilibrium constant (K) for this reaction at the given temperature, which would need to be known to provide a precise answer.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.
