Final answer:

The formation of ozone from oxygen is not spontaneous at room temperature under standard state conditions, therefore the statement is b. false.

Step-by-step explanation:

The formation of ozone (O3(g)) from oxygen (O2(g)) is indeed an endothermic process, which means it requires the input of energy to proceed. At room temperature under standard state conditions, the formation of ozone is not spontaneous because it does not occur without an external energy source such as ultraviolet radiation or an electric discharge. Therefore, the correct statement is B) False.

The given standard free energy of formation (ΔG°f, O3 = 163.2 kJ/mol) indicates that the reaction is not favored to proceed spontaneously at room temperature under standard conditions. Instead, ozone formation occurs readily in the upper atmosphere where it is driven by UV light or artificially through processes involving electrical discharge.
