The reaction a→ b is to be carried out isothermally in a continuous-flow reactor, to consume 99% of a (ca = 0.01 cao). the entering molar flow rate is 5 mol/min, and the entering volumetric flow rate is 10 l/min. the reaction rate -ra is first order in a, and the reaction rate constant is 0.36 min-1.

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.
