Question

how changing temperature can change concentration of components in an equilibrium?

Answer 1

When the temperature of an equilibrium mixture is increased, the rate of both reactions increases , but the rate of the endothermic reaction (the reaction that absorbs the added energy) is increased more.

Answer 2

Also, at a given temperature, the vapor has a particular pressure; if the temperature is increased, it has a higher pressure. Increasing the temperature causes the equilibrium to shift toward a higher concentration of vapor, but, if the system is maintained at that higher temperature, equilibrium will again be established.

Answer 4

@JoannaBlackwelder is correct :)

Answer 5

vapor pressure is not my concern. i mean equilibrium in a solution.
when temperature increased rate of endothermic reaction increase but more than exothermic reaction.
as a consequence rate of reactions is not equal.is that what you meanJoannaBlackwelder?

Answer 6

what do you think @minimoo , @smartypantsjay , @ganeshie8 ?

Answer 7

i say @joannaBlackwelder is spot on

Answer 8

but he says rate of one of them is more than another.It isn't an equilibrium.in equilibrium rate of both reaction must be same. am i right @minimoo ?

Answer 9

The rates are equal at equilibrium. However, when you change the temperature you disturb the equilibrium and the rates could be different.
