Given the following reaction: h2(g)+i2(s) → 2hi(g) with a ∆h of 52.9 kj. what is the change in enthalpy for the following reaction: hi(g) → 1 2h2(g)+1 2 i2(s)? express your answer in kj.

The change in enthalpy of the reaction is -26.45 kJ

Explanation:

The given chemical reaction follows:

The enthalpy change of the reaction when 2 moles of HI is formed is 52.9 kJ

Now, the chemical reaction for which enthalpy change is to be calculated is:

Sign for enthalpy change will be reversed, because the reaction is reverse.

By Stoichiometry of the reaction:

When 2 moles of Hi is reacted, the enthalpy change of the reaction is -52.9 kJ

So, when 1 mole of HI will be reacted, the enthalpy change of the reaction will be =

Hence, the change in enthalpy of the reaction is -26.45 kJ

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
