Consider the following reactions at 25°C: 2NO(g) ⇌ N2(g) + O2(g) Kc = 1x1030 2H2O(g) ⇌ 2H2(g) + O2(g) Kc = 5x10-82 2CO(g) + O2(g) ⇌ 2CO2(g) Kc = 3x1091 Which compound is most likely to dissociate and give O2(g) at 25°C?

personal, she chose to do it.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
