The decomposition of iodoethane in the gas phase proceeds according to the following equation: C2H5I(9) C2H4 (9) + HI(g) S At 660. K, k = 7.2 × 10-4 s¹; at 720. K, k = 1.7 x 10-2 s-1. What is the value of the rate constant for this first-order decomposition at 355°C? Rate constant = If the initial pressure of iodoethane is 731 torr at 245°C, what is the pressure of iodoethane after three half-lives? Pressure = torr
