<h2>Endothermic and Exothermic</h2>

Explanation:

An exothermic response discharges heat and endothermic absorbs to heat
The whole of the enthalpies of the reactants is more prominent than the product, the response will be exothermic
In the product that the items side has a bigger enthalpy, the reaction is endothermic
An exothermic method is one that emits heat. This heat is transferred to the environment
An endothermic reactions is one in which heat must be provided to the system from the environment

egoroff_w [7]

Answer:

K = 0.2

Explanation:

Based on the chemical dissociation of N₂O₄:

N₂O₄ ⇄ 2NO₂

The equilibrium constant, K, of the reaction is:

K = [NO₂]² / [N₂O₄]

Now, if 20% of N₂O₄ is dissociated, 80% remains as N₂O₄ = 0.8mol/L = 0.8M

as 20% is dissociated, 0.2moles of N₂O₄ were dissociated and 0.2*2 = 0.4mol/L of NO₂ are produced.

Replacing in K:

K = [0.4M]² / [0.8M]
