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

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
