Using the values given of standard enthalpies of formation, calculate the ΔHreactiono for the formation of NO2(g). 2NO(g)+O2(g)⇋2NO2(g)

O2(g): 0 kJ/mol
NO(g): 90.25 kJ/mol
NO2(g): 33.18 kJ/mol

C

Explanation:

Weak acid and base ionization reactions and the related equilibrium constants, Ka, and Kb. Relating Ka and Kb to pH, and calculating percent dissociation. ... bases refer to species that completely dissociate to form ions in solution. ... Problem 1: Weak vs. strong acids at the same concentration ... Acid-base properties of salts.

So your answer is C.

Hope this helps! <3
