Consider this three-step mechanism for a reaction: Cl2(g)⇌k2k12 Cl(g)Cl(g)+CHCl3(g)→k3HCl(g)+CCl3(g )Cl(g)+CCl3(g)→k4CCl4(g)FastSlowFas t Cl2(g)⇌k2k12 Cl(g)Cl(g)+CHCl3(g)→k3HCl(g)+CCl3(g )Cl(g)+CCl3(g)→k4CCl4(g)FastSlowFas t What is the overall reaction? Identify the intermediates in the mechanism. What is the predicted rate law?

Can anyone (a-level) a student was analysing a carbonate compound, mco3, containing an unknown group 2 metal, m. the student carried out thermal decomposition on 0.730g of the carbonate and measured the volume of gas produced. mco3 (s) mo (s) + co2 (g) the student collected and measured 120cm3 of carbon dioxide. 1 mol of carbon dioxide occupies 24 000 cm3 under these conditions. calculate the molar mass of the group 2 carbonate and hence deduce the identity of the group 2 metal, m.
