Determine the missing value of ΔS⁰298 (in J/K/mol). N(g) + O(g) → NO(g)
ΔS⁰298 = ?
N2(g) + O2(g) → 2 NO(g)
ΔS⁰298 = 24.8 J/K/mol
N2(g) → 2 N(g)
ΔS⁰298 = 115.0 J/K/mol
O2(g) → 2 O(g)
ΔS⁰298 = 117.0 J/K/mol

At a temperature of 393 k, the temperature of a sample of nitrogen is 1.07 atm what will the pressure be at a temperature of 478 k

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
