Consider the following equilibrium: A2 (g) + B2 (g) ⇋ 2 AB (g)
If the value of Kc for this reaction is 116.4, and the initial concentrations of each species are: [A2] = 0.200 M, [B2] = 0.200 M, [AB] = 0.770 M , what will be the equilibrium concentration of AB (in M)?

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.
