The gas phase reaction Cl2 + 3 F2→2 CIF2 has a rate law that is second order with respect to fluorine concentration but zero order with respect to chlorine. The rate constant, kis 1.40x103 mol1 Ls1. If the initial concentrations are 0.20 mol L-1 chlorine is and 0.13 mol L-1 fluorine, calculate the initial reaction rate and therefore the change in fluorine concentration over the first 2.3 seconds of reaction. (Note the choices below may be given in 'exponential' format, e.g. 0.0012 = 1.2x103 would be displayed as 1.2e-3) O -5.4e-5 mol/L O 5.4e-5 mol/L 2.4e-5 mol/L O -3.9e-4 mol/L O -1.6e-4 mol/L O -7.1e-5 mol/L O -1.8e-5 mol/L
