In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

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.

Answer explain why it is not possible to deduce a complete order of reactivity.
