It's because is negative, which places (RT) in the denominator. This is how the equation will now appear.
Here you can observe the value of is greater than

The number of moles of gas that move from the reactant side to the product side is denoted by the symbol ∆n or delta n in this equation.
Once more, n represents the growth in the number of gaseous molecules the equilibrium equation can represent. When there are exactly the same number of gaseous molecules in the system, n = 0, Kp = Kc, and both equilibrium constants are dimensionless.
<h3>Definition of equilibrium</h3>When a chemical reaction does not completely transform all reactants into products, equilibrium occurs. Many chemical processes eventually reach a state of balance or dynamic equilibrium where both reactants and products are present.

<u>Answer:</u> The amount of energy required to convert ammonia back to hydrogen and nitrogen is 45.9 kJ
<u>Explanation:</u>
Endothermic reactions are defined as the reactions in which energy is absorbed in the reaction. The enthalpy change of the reaction is positive.
Exothermic reactions are defined as the reactions in which energy is released in the reaction. The enthalpy change of the reaction is negative.
For the given chemical equation:
In the above reaction, the enthalpy change is negative. So, the reaction is exothermic in nature.
For the reverse reaction, the magnitude of the enthalpy change remains the same but sign for it changes.
Hence, the amount of energy required to convert ammonia back to hydrogen and nitrogen is 45.9 kJ
