The equilibrium constant is the ratio of the concentration of the products and the reactants. Thus, option a is accurate.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant is the reaction quotient of the products of the reactants of the reaction mixture. It is represented by K and varies at different temperatures.
At different temperatures, the value of K varies as the reaction shifts when the temperature is increased or decreased. Also, the value of the K is not always close to 1.
Therefore, option a ratio of concentration is accurate.

ZnO + C → Zn + CO
I don't know what oxidised an reduced means
Enthalpy refers to the total energy of a system. Hope this helped!
Answer:
P₄ + 5O₂ → 2P₂O₅
Explanation:
Phosphorus burn in the presence of air and produced diphosphorus pentoxide.
Chemical equation:
P₄ + O₂ → P₂O₅
Balanced chemical equation:
P₄ + 5O₂ → 2P₂O₅
Equation is balanced because there are four phosphorus atoms ans ten oxygen atoms in both side of equation.
Coefficient with reactant and product:
P₄ 1
O₂ 5
P₂O₅ 2
