Question

Please help me ow to get to a T?

For the first one I had:

ΔH^⁰_rxn = 2 ΔHf⁰(NOCl) – [2ΔHf⁰(NO)+ ΔHf⁰Cl₂] = 2*51.7 kJ/mol – [2*91.3 kJ/mol +0 kJ/mol] = -79.2 kJ= -79200J

ΔS^⁰_{rxn =}2 ΔS⁰(NOCl) – [2ΔS⁰(NO)+ ΔS⁰Cl₂] =2*261.7 J/K·mol – 2*210.8 J/K·mol-223.1 J/K·mol = -121.3J/K

- How do I get a ΔT?

-Also, what does it mean:

The reaction is spontaneous above or spontaneous below?

$Calculate the temperature at which each of the following reactions becomes spontaneous. (a) \( 2 \mathrm{NO}(g)+\mathrm{Cl}_{$
