removing heat from system

[davidryan3f]

If a reaction is exothermic, will the temperature always decrease? In not, what are the exceptions to this rule?

[keyaluo4C]

The definition of an exothermic reaction is one that releases heat.

[Ashley Fang 2G]

Yes, if a reaction is exothermic, it will always release energy and delta H will always be less than 0.

[Juliana Chopelas 1A]

Exothermic reaction will always have a decrease in temperature as energy is being released. Once the temperature rises it will switch to endothermic as energy is being absorbed.

[Cooper Baddley 1F]

Exothermic means it releases heat so yes it will mean the temperature of the system decreases

[Diana Andrade_4F]

Yeah, if a reaction is exothermic then temp will decrease. This is because the reaction is releasing heat (delta H is negative).

[Jaklin Astvatsatryan]

If Kc decreases with an increase in temperature, the reaction shifts to the left, making it an exothermic reaction. The Kc can also increase with a decrease in temperature, causing the reaction to shift to the right.
