If a chemical reaction has reached equilibrium and you lower the pressure of the system while keeping the temperature constant what happens to the equilibrium of the reaction?
PaniniG
If all the reactants occupy more volume than all of the products, the reverse reaction will be favored. If all the reactants occupy less volume than all of the products, the forward reaction will be favored. If the products and reagents have the same volume, the equilibrium will not change.

What is the effect of pressure and concentration on Kc and Kp values?
Kc is the equilibrium constant of a chemical reaction related to concentrations. Kp is the equilibrium constant of a chemical reaction related to pressures. Generally, in normal conditions the effect of temperature is not so important.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant?
Heat of reaction.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant there will be no affect on the?
Heat of reaction.
What is thermodynamic equilibrium?
At thermodynamic equilibrium the dynamic processes for changes in a system have reached a steady state (not changing with time) where temperature has stabilized to a constant, no heat is being exchanged, no work is occurring, composition is constant (reactants are being converted to products at the same rate that the products are converting back to the reactants), pressure is constant, if there is more than one phase, movement between the phases is balanced (for example evaporation and condensation are occurring at the same rate), and there are no concentration gradients.
What states that the solubility of gas is directly proportional to its pressure at a constant and specific temperature?
Henry's Law:At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the Partial_pressureof that gas in equilibrium with that liquid.
What are Kp aND KC?
Kc is the equilibrium constant of a chemical reaction; Kp is the equilibrium constant of a chemical reaction at constant pressure.

Heat of reaction.
Why does constant Kc in chemical equilibrium has no units?
Kc is the equilibrium constant and is the ratio of the activity of the reactants (numerator) to the activity of the product (denominator). The activity of each component is raised to the power of its corresponding chemical stoichiometric coefficient. Since the activity of each chemical is unitless, the equilibrium constant will also have no units. Example: For equilibrium of chemicals in the gas phase, each activity will be measured by its partial pressure (units of pressure) multiplied by its fugacity (units of 1/pressure), so the activity of each gas participating in the equilibrium will be unitless, and the corresponding ratio (Kc) will be unitless.
Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
No.
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
What is thermodynamic equilibrium?
At thermodynamic equilibrium the dynamic processes for changes in a system have reached a steady state (not changing with time) where temperature has stabilized to a constant, no heat is being exchanged, no work is occurring, composition is constant (reactants are being converted to products at the same rate that the products are converting back to the reactants), pressure is constant, if there is more than one phase, movement between the phases is balanced (for example evaporation and condensation are occurring at the same rate), and there are no concentration gradients.
When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
What is the LeChatlier?
The Chatelier's Principle states that when a dynamic equilibrium is disturbed by changing conditions then the position of equilibrium shifts to counteract the change to reestablish equilibrium. A chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products , equilibrium will shift in opposite directions to offset change.
When the temperature of of gas increases at constant pressure its?
As pressure increases, if temperature is constant, the gas will decrease in volume.
