X + Y XY + heat What happens as the temperature is increased? [X] remains constant. [X] increases. [X] decreases.
2 answers:
Answer: [X] increases.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
This is a type of Exothermic reaction because heat is released in the reaction.
If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where decrease in temperature occurs. As, this is an exothermic reaction, reverse reaction will decrease the temperature. Hence, the equilibrium will shift in the backward direction and thus [X] increases.

Answer: Equilibrium constant is 0.70.
Explanation:
Initial moles of = 0.35 mole
Volume of container = 1 L
Initial concentration of
Initial moles of = 0.40 mole
Volume of container = 1 L
Initial concentration of
equilibrium concentration of [/tex]
The given balanced equilibrium reaction is,
Initial conc. 0.35 M 0.40M 0 0
At eqm. conc. (0.35-x) M (0.40-x) M (x) M (x) M
The expression for equilibrium constant for this reaction will be,
we are given : (0.35-x)= 0.18
x = 0.17
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is 0.70.
