The balanced equation for the reaction between nitrogen and hydrogen to form ammonia is N₂(g) + 3H₂(g) --> 2NH3(g). This uses the concept of balanced chemical equations, which ensure the same number of atoms of each element on both sides.
The reactants in the question are hydrogen and nitrogen, and they react to form the product, ammonia. This reaction can be described using a balanced chemical equation, which ensures that the number of atoms of each element are the same on both the reactant and product sides of the equation.
The balanced equation for this reaction is N₂(g) + 3H₂(g) --> 2NH3(g). Here, N₂ represents nitrogen, H₂ represents hydrogen, and NH₃ represents ammonia. The 'g' in brackets indicates that these compounds are in their gaseous states. The numbers in front of the chemical formulas are called stoichiometric coefficients and they indicate the ratio in which the reactants react and the products form. In this case, one nitrogen molecule reacts with three hydrogen molecules to yield two ammonia molecules.
Chemical reactions, including this one, proceed from left to right as shown by the arrow. They show how reactants become products, similar to mathematical equations.

The alpha decay of Radon-198 produces alpha particle and ¹⁹⁴₈₄Po.
Alpha decay is a type of radioactive disintegration in which some unstable atomic nuclei spontaneously expel an alpha particle to dissipate excess energy.
Alpha decay of Radon-198 is shown as:
¹⁹⁸₈₆Rn → ⁴₂He + ¹⁹⁴₈₄Po
In the above decay from the parent nuclei, daughter nuclei (¹⁹⁴₈₄Po) and alpha particle (⁴₂He) is produced.
Hence daughter nuclei of the alpha decay of Radon-198 is ¹⁹⁴₈₄Po.

600k as well as 50kPa since the pressure seems to be the lowest as well as the temperature is the greatest throughout this situation.
Under high temperatures and low pressures, actual gases behaved like ideal gases. such as the rule
Even though at high temperatures, the kinetic energy of such gas particles surpasses the intermolecular attractive forces, — in other words this same potential energy of something like the molecules (gaseous).
Thus the above answer i.e., "option 4" is right.
