In the stratosphere, chlorine atoms catalytically destroy ozone (O3) producing the now infamous ozone hole above the Antarctic pole. An intermediate compound of this process is chlorine monoxide (ClO), before chlorine is bound and rendered inactive by the formation of chlorine nitrate (ClONO2). Perform a steady-state analysis for d[Cl]/dt and for d[ClO]/dt in the following mechanism:
Cl2 → 2 ClCl + O3 → ClO + O22 ClO →2 Cl + O2ClO + NO2 → ClONO2
Obtain expressions for the steady-state concentrations of Cl and ClO and hence for the rate of change of ozone.
Normally the alkaline earth carbonates (MCO3; M = Mg^2+, Ca^+2, Sr^+2, Ba+2) are insoluble in water. Why would the method used in this experiment work for calculating the molar mass of the alkaline earth? How would the calculations have to be cha..
