The synthesis of NH3 is represented by the equation above. based on the equilibrium constant, K and delta H rxn given above, which of the following can best be used to justify that the reaction is thermodynamically favorable at 298 K and constant pressure? N2 (g) + 3H2 (g) --> 2NH3 (g)
K= 5.6 × 10^5 at 298 K
delta H rxn= -91.8 kj/mol

Explanation:

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
