What else can I help you with?
What will happen to the reaction mixture at equilibruim if the volume of the container is increased?
The equilibrium will be re-established.
Why does planetary cooling happen?
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
Hat will happen when a reactant is added to a system at equilibrium?
The concentrations of reactants and products are modified.
What happens if a mixture is melted beyond its melting point?
You cannot melt something pass the melting point. You can simply increase its temperature. The only thing that would happen is that it would start to boil and then the mixture could explode, evaporate, release a gas, etc. It is like taking water and heating it to 400 degrees. What would happen?
Does dynamic equilibrium always happen when a change occurs?
No, this is not necessarily.
What causes the equilibrium to shift to the left?
The equilibrium shifts to the left when there is an increase in the concentration of reactants or a decrease in the concentration of products. This can also happen when the temperature is decreased in an exothermic reaction.
What would happen to a system at equilibrium if the temperature changed?
If the temperature of a system at equilibrium changed, the equilibrium position would shift to counteract the change. If the temperature increased, the equilibrium would shift in the endothermic direction to absorb the excess heat. If the temperature decreased, the equilibrium would shift in the exothermic direction to release more heat.
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.
What would happen to a a system at equilibrium if the temperature were changed?
the equilibrium constant would change
What would happen to a system a equilibrium if the temperature were changed?
the equilibrium constant would change
What will happen to the reaction mixture at equilibruim if the volume of the container is increased?
The equilibrium will be re-established.
What happen to the movement of molecules at equillimbrium?
The movement of molecules at equilibrium is determined by Le Chatalier's principle. This basically says that if you change a reaction to favour one side, the equilibrium will try and counteract this change. The three things that can affect an equilibrium is temperature, pressure and concentration.
What needs to happen for thermal energy to be transferred and what needs to happen at thermal equilibrium?
You have to have two objects at different temperatures near each other, when two or more objects have the same temperature.
What would happen if the equilibrium of a weak dissociation reaction were upset?
The reaction would shift to balance the change
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
What will happen to gas pressure when the volume is decreased?
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
Why does planetary cooling happen?
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
