Nitrosyl chloride, NOCI, dissociates on heating as shown below. When a 1.50 gram sample of pure NOCI is heated at 350°C in a volume of 1.00 liter, the percent
dissociation is found to be 57.2%. Calculate Kc for the reaction as written.
NOCI(9) = NO(g) + 12 Cl2(9)

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.
