Decreasing the temperature of the reaction 3H2 + N2<----->2NH3. In this reaction, the product absorbs heat. WHICH WAY WILL
AURORKA [14]

3H_{2}+N_{2}⇔2NH_{3}

Decreasing the temperature of the reaction,the reaction shifts forward.

The explanation is given below.

Explanation:

If the temperature of the reaction mixture is increased,then the equilibrium will shift to decrease the temperature.

If the temperature of the reaction mixture is decreased,then the equilibrium will shift to increase the temperature.

During the formation of the ammonia,it gives off heat.So it is an exothermic reaction.

3H_{2}+N_{2}⇔2NH_{3}

A decrease in the temperature favors the reaction that is exothermic (the forward reaction)because it produces energy.Therefore,if the temperature is decreased,the yield of the ammonia increases.

<em>Therefore if the temperature is increased,the reaction shifts forward and the yield of the ammonia increases and it is an exothermic reaction.</em>

During what meterological (weather) changes does sublimation occur on earth?
insens350 [35]
Sublimation occurs more readily when definite weather circumstances are present such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes where the air pressure is less than at lower altitudes and energy such as strong sunlight is also needed. Sublimation happens a lot in the south face of Mt. Everest which have low temperatures, strong winds, intense sunlight, very low air pressure and the recipe for sublimation to occur.
