Decomposition of N2O5 in CC14 at 45°C is known to follow a First-order kinetics. The specific rate constant for this decomposition process at the above temperature is 6.32 × 10¬* s. (a) If the initial concentration of N2O5 was 0.500 M, then what will be the concentration of N2O5 remaining (not decomposed) after 2.00 hr? (b) For 90% of the N2O5 to decompose, how much time will be required? (c) From the following decomposition data of N2O5, calculate the activation energy (Ea). T1 = 35°C, kị = 6.60 ×10-5 s=1 and T2 = 65°C, k2 = 2.40 ×10-3 s-1.
