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.
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 energy is removed from a system at equilibrium, resulting in a decrease in temperature, the system will typically shift in a direction that helps to counteract this change, according to Le Chatelier's principle. If the system involves an exothermic reaction, it may favor the forward reaction to release heat and restore equilibrium. Conversely, if the reaction is endothermic, it may shift toward the reverse reaction to absorb heat. Ultimately, the system will adjust to restore a new state of equilibrium at the lower temperature.
Le Chatelier's principle states that a system at equilibrium will shift in a way that counteracts the change imposed on it, such as increasing temperature. In the case of increasing temperature, the system will shift in the endothermic direction to absorb the added heat.
To shift the equilibrium to the right in a chemical system, you can increase the concentration of the reactants, decrease the concentration of the products, or increase the temperature if the reaction is endothermic. Additionally, removing a product or adding a catalyst may also help facilitate the forward reaction without changing the overall equilibrium position. Changes that favor the formation of products will effectively drive the equilibrium to the right.

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.
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.
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.
Changing the temperature will change Keq. (apex.)
If you raise the temperature, the endothermic reaction will increase to use up the extra heat, therefore producing less percentage yield of ethanol and more of ethene and steam.
The temperature of a reaction will entirely change th equilibrium position for any given reaction. If I'm right, as you increase the temperature, the equilibrium shifts closer to the endothermic reaction as there is more heat to consume. It may also, of course, change other properties of the substances involved in the reaction, but that depends on the chemicals.

be an endothermic reaction. This means that the products have more energy than the reactants. Examples include photosynthesis and the melting of ice.
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.

endothermic reaction. because as you may have seen, high temperatures are required to speed up the reaction. this is because, since the reaction in endothermic, high temperatures would cause the equilibrium to shift forward to decrease the temperature thus leading to the formation of more esters thereby speeding up the reaction (le chatelier's principle).
