The Decomposition of in Solution in Carbon Tetrachloride

question 82

Multiple Choice

The decomposition of The decomposition of     in solution in carbon tetrachloride proceeds via the reaction 2 N<sub>2</sub>O<sub>5</sub>(soln) → 4 NO<sub>2</sub>(soln) + O<sub>2</sub>(soln)  The reaction is first order and has a rate constant of 4.82 × 10<sup>-3 </sup>s<sup>-1</sup> at 64°C.If the reaction is initiated with 0.058 mol in a 1.00-L vessel,how many moles remain after 151 s? A)  0.055 M B)  0.060 M C)  0.028 M D)  12 M E)  2.0 × 10<sup>3</sup> M The decomposition of     in solution in carbon tetrachloride proceeds via the reaction 2 N<sub>2</sub>O<sub>5</sub>(soln) → 4 NO<sub>2</sub>(soln) + O<sub>2</sub>(soln)  The reaction is first order and has a rate constant of 4.82 × 10<sup>-3 </sup>s<sup>-1</sup> at 64°C.If the reaction is initiated with 0.058 mol in a 1.00-L vessel,how many moles remain after 151 s?
