For the reaction 2n 2o(g) ⇌ o 2(g) + 2n 2(g), what happens to the equilibrium position if the pressure increases?

Equilibrium will shift in forward direction.

Explanation:

According to Le Chatelier's Principle, the change in any state of the equilibrium say temperature, volume, pressure, or the concentration, the equilibrium will oppose these changes and will shift in such a way that the effect cause must be nullified.

Effect of the change in the pressure :

If the pressure is increased , the equilibrium of the reaction is disturbed , so , the reaction will move in order to decrease the pressure.

The molecules of gas are responsible for the pressure and thus to nullify this effect or to decrease the pressure, the equilibrium will shift in a direction where there are less number of gaseous molecules.

For the reaction given ,

2N₂O (g) ⇄ O₂(g) + 2N₂(g)

The number of gaseous molecules in the product (2) is less than the reactant (2 + 1), so the equilibrium will shift in forward direction.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
