Question 11 of 42 Organic compounds that contain large proportions of nitrogen and oxygen tend to be unstable and are easily decomposed. Hexanitroethane, C₂(NO₂)6, decomposes according to the equation C₂(NO2)6→ 2NO2+4NO+2CO₂ The reaction in CCl4 solvent is first order with respect to C₂(NO₂)6. At 67.3 °C, k = 0.000384 s¹ and at 119.1 °C, k = 0.0207 s¹¹. (a) What is the half-life of C₂(NO₂)6 at 67.3 °C? i (b) What is the half-life of C₂(NO₂)6 at 119.1 °C? i seconds (c) If 0.100 mol of C₂(NO2)6 is dissolved in CCl4 at 67.3°C to give 1.00 L of solution, what will be the C₂(NO₂)6 concentration after 50.0 minutes? i M (e) What is the rate constant at 158.7 °C? i seconds (d) What is the value of the activation energy of this reaction, expressed in kilojoules? i $1 kJ/mol
