The decomposition of N2O5 in solution in carbon tetrachloride proceeds via the reaction 2N2O5 (soln) → 4NO2 (soln) + O2 (soln) The reaction is first order and has a rate constant of 4.82 x 10^-3 s^-1 at 64 degrees C. If the reaction is initiated with 0.072 mol in a 1.00-L vessel, how many moles remain after 151 s? a) 0.067 M b) 1.6x10^3 M c) 9.6 M d) 0.074 M e) 0.035 M
