Question

how increasing temperature can change position of equilibrium? speak in details please.

Answer 1

As temperature goes up, a solid becomes a liquid and a liquid becomes a gas. So the increase in temperature shifts the equilibrium towards the liquid and gas phases.

Answer 2

Looked at another way, increasing the temperature is like adding energy into the system, causing the system to shift from its resting/equilibrium point to a different point where it can rest/be at equilibrium.

Answer 3

i mean chemical equilibrium .

Answer 4

\[\Delta G=\Delta H-T \Delta S\] As T(temperature) increases, G becomes more negative, indicative of a reaction more likely occurring thus shifting equilibrium towards the products.

Answer 5

please speak about rate of reaction and effects of temperature on it.

Answer 6

Generally, the rate of a reaction increases as temperature increases.

Answer 7

rate of backward and forward reactions increase equal by increasing temperature. is that what you mean?

Answer 8

No. An increase in temperature generally favors the reaction that increases entropy. For example, imagine an ice cube at freezing temperature. At that temperature, it is at equilibrium between its solid and liquid forms. When temperature increases, the ice melts and you see a noticeable increase in water. Here, the equilibrium is broken and water is favored over ice as that is more entropically favorable. The same analogy applies to chemical reactions.
