Question 8 of 12 Map sapling learning Substance (kJ/mol) Consider the decomposition of a metal oxide to its elements, where M represents a generic metal -9.30 M(s) O2(9) 0 What is the standard change in Gibbs energy for the reaction, as written, in the forward direction? Number k.J/ mol What is the equilibrium constant of this reaction, as written, in the forward direction at 298 K? Number What is the equilibrium pressure of O2(g) over M(s) at 298 K? Number atm Previous Give Up & View Solution e Check Answer Next Exit Hint

Explanation / Answer

delta G of reaction = delta G of products - delta G of reactants

keeping values from given table

delta G of reaction = 9.3 KJ

delta G = -RTln K

K =e ^-deltaG / RT = 0.0235

Kp = 0.0235

pO23/2 = 0.0235

pO2 = 0.0820 atm
