This is an endothermic equilibrium reaction
Thus, increase temperature will push the reaction to the right.
So more N2O4 is produced

This equilibrium is caracterised with ΔH = −57.23 kJ/mol (ΔQ = +57.23 kJ/mol, which is exothermic to the right).
So more NO2 is present at higher temperatures as it shifts this equilibrium to the left hand side.

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 will happen to the reaction mixture at equilibruim if the volume of the container is increased?
The equilibrium will be re-established.
What happens to the equilibrium if the pressure is increased?
equilibrium will shift to the side of the equation with the least moles in attempt to reduce pressure in the haber process N2+3H2 <--> 2NH3 an increase in pressure causes equilibrium to shift the right because it has the least moles (2 instead of 4) <--> represents a reversible reaction sign
Does addition of noble gas effect partial pressures in gaseous equilibrium system?
Yes. If the pressure is increased, even with a noble gas, the reaction equilibrium will shift to alleviate and lower that increased pressure (if there are more moles of gas on one side of the reaction than the other).
Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The value of the equilibrium constant K is only influenced by temperature.
What happens to the reaction 2NO2 N2O4 57.2 kJ when the temperature of the reaction is increased?
This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced
What temperature is the reaction at equilibrium?
The temperature will depend on the reaction that is under consideration.
why are many industrial reaction carried out at high tempratureexplain the reason by having given illustrated example?
Because if the temperature is increased, the equilibrium position moves in the direction of the endothermic reaction. and if the temperature is low the reaction would be slow.
At what temperature is the reaction at the equilibrium?
430 k
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 increasing temperature effect endothermic reaction?
You can use LeChatelier's Principle to solve this problem. For an endothermic reaction A+heat<-->B Thus, by increasing the heat, you are shifting the equilibrium towards the reactants. The reaction will adjust itself by shifting the equilibrium to the right (producing more of the product).

How would the yield of ethanol at equilibrium change if the temperature was increased?
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.
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.
What piece of information will tell you which way the equilibrium of a reaction will shift due to a change in temperature?
The enthalpy of the reaction.
Does addition of noble gas effect partial pressures in gaseous equilibrium system?
Yes. If the pressure is increased, even with a noble gas, the reaction equilibrium will shift to alleviate and lower that increased pressure (if there are more moles of gas on one side of the reaction than the other).
