A sample of Br2 and H2 gas is irradiated with light with a wavelength range between 440 and 500 nm. It is known that this radiation has enough energy to obtain HBr. With this data, indicate the valid options (explain it). Also explain the invalid ones.a) All the molecules present will give rise to HBr, because the wavelengths are appropriate to activate all the reactants.b) The rate of HBr formation depends directly on the concentration of H2 in the sample.c) The rate of HBr formation depends directly on the concentration of Br2 in the sample.d) If the sample is irradiated with a wavelength of 580 nm, there is no guarantee that HBr will be obtained.
