The Decomposition of N₂O₅ in Solution in Carbon Tetrachloride Proceeds

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 × 10^-3 s^-1 at 64 °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
B) 0.074
C) 0.035
D) 9.6
E) 1.6 × 10³
