Effects of temperature and pressure on exothermic and endothermic reaction?
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
When the heat shifts the direction of the reaction there has been a change in concentration and equilibrium will then be affected?
Yes, a change in temperature can shift the equilibrium of a reaction by changing the concentrations of reactants and products. The direction of the shift depends on whether the reaction is endothermic or exothermic. An increase in temperature will favor the endothermic reaction, while a decrease will favor the exothermic reaction.
Where does the equilibrium shift in an exothermic reaction?
In an exothermic reaction, heat is released as a product. According to Le Chatelier's principle, if the temperature of the system is increased, the equilibrium will shift to the left, favoring the reactants to absorb the excess heat. Conversely, if the temperature is decreased, the equilibrium shifts to the right, favoring the formation of products to release heat.
How does temperature effect kc kp?
The equilibrium constants ( K_c ) and ( K_p ) are affected by temperature due to the principle of Le Chatelier, which states that a system at equilibrium will shift to counteract changes in conditions. For exothermic reactions, increasing temperature decreases ( K_c ) and ( K_p ), while for endothermic reactions, increasing temperature increases these constants. This is because temperature influences the position of equilibrium, favoring either the reactants or products based on the heat exchange associated with the reaction.
When a reaction is at equilibrium increasing the temperature favors the reaction that releases energy as heat.?
This is False!!! According to LeChatlier's Principle, increasing the temperature is a strees on the equilibrium. To relieve that stress the reaction will shift producing more of the substances on the side of the reaction that absorbs heat energy.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
How does temperature affect the Keq of a reaction?
Changing the temperature will change Keq. (apex.)
How does a change in temperature affect the equilibrium shift of a chemical reaction?
A change in temperature can affect the equilibrium shift of a chemical reaction by either favoring the forward reaction (endothermic) or the reverse reaction (exothermic). When the temperature increases, the equilibrium will shift towards the endothermic direction to absorb the excess heat. Conversely, when the temperature decreases, the equilibrium will shift towards the exothermic direction to release heat.
How does increasing temperature affect the shift of equilibrium in a chemical reaction?
Increasing temperature can shift the equilibrium of a chemical reaction by favoring the endothermic or exothermic direction, depending on the specific reaction. This shift occurs because higher temperatures provide more energy for reactant molecules to overcome activation energy barriers, leading to an increase in the rate of the forward or reverse reaction.
Effects of temperature and pressure on exothermic and endothermic reaction?

How will increasing the temperature affect the equilibrium?
It depends if the reaction is exothermic or endothermic. For example: If the reaction requires energy (endothermic), then energy (i.e. 100kJ) will be a reactant on the left-hand side. Then, use Le Chatelier's Principle from there. If you increase the temperature of the system in equilibrium, it will shift towards the product/right-hand side. If you decrease the temperature of the system, it will shift towards the reactants/left-hand side.
What piece of information will tell you which way the equilibrium of a reaction will shift due to a change in temperature?
The sign of the enthalpy change (∆H) of the reaction will indicate the direction in which the equilibrium will shift with a change in temperature. If ∆H is negative (exothermic reaction), an increase in temperature will shift the equilibrium towards the reactants; if ∆H is positive (endothermic reaction), an increase in temperature will shift the equilibrium towards the products.
When the heat shifts the direction of the reaction there has been a change in concentration and equilibrium will then be affected?

The direction of the shift depends on whether the reaction is endothermic or exothermic.

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.
When a reaction is at equilibrium increasing the temperature favors the reaction that releases energy as heat.?
This is False!!! According to LeChatlier's Principle, increasing the temperature is a strees on the equilibrium. To relieve that stress the reaction will shift producing more of the substances on the side of the reaction that absorbs heat energy.
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.
