Explanation:
In liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
So, when at 298 K and 1 atm 
exists in liquid state and 
exists as a gas then it means there occurs strong force of attraction between the molecules of due to which it exists in liquid form.
Thus, we can conclude that at 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among 
molecules are greater than those among 
molecules.
The electronic configuration is for iron (Fe) because if you add all those power up it will give you 26 and it’s the atomic number of Fe
A catalysts lowers activation energy
Answer:
1. C(s) + O₂(g) ⇄ CO₂(g)
2. ![K=\frac{[CO_{2}]}{[O_{2}]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BCO_%7B2%7D%5D%7D%7B%5BO_%7B2%7D%5D%7D)
Explanation:
<em>When the oxide of generic metal M is heated at 25.0 °C, a negligible amount of M is produced. MO₂( s ) ⇄ M(s) + O₂(g) ΔG° = 290.2 kJ/mol.</em>

<em>1. When this reaction is coupled to the conversion of graphite to carbon dioxide, it becomes spontaneous. What is the chemical equation of this coupled process? Show that the reaction is in equilibrium. Include physical states and represent graphite as C(s).</em>
The chemical equation for the coupled reaction is:
C(s) + O₂(g) ⇄ CO₂(g)
<em>2. What is the thermodynamic equilibrium constant for the coupled reaction?</em>
The thermodynamic equilibrium constant (K) is the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients. Only gases and aqueous species are included.
Here Ecell = 0, and ∆G = 0, and Q = K equation are three relationships are true at equilibrium.
