Answer to Question #349579 in General Chemistry for jrs

Question

Dinitrogen pentaoxide, N₂O5, decomposes to nitrogen dioxide, NO2 and oxygen, O₂ as shown in the reaction below: 2N₂O5(g) →→→ 4NO2(g) + O₂(g) Initial rate decomposition data at 25° C for the decomposition give the following data: Concentration of N₂O5, M Initial rate, mol/L-min 0.250 5.70 x 10-4 0.350 7.98 x 10-4 0.450 1.03 x 10-3 Calculate the rate constant at 25°C ? min-¹ What is the half-life for the reaction at 25°C ? min How long will it take to decompose 40.0% of N₂O5 at 25°C ? min At 40°C, the rate constant for the decomposition is 1.58 x 10-2 min¹. What is the activation energy for this reaction? kJ/mol
