For the zero-order decomposition of HI on a gold surface HI (g) →Au1/2 H2 (g) + 1/2 I2(g) it takes 16.0 s for the pressure of HI to drop from 1.00 atm to 0.200 atm. (a) What is the rate constant for the reaction?(b) How long will it take for the pressure to drop from 0.150 atm to 0.0432 atm?(c) What is the half-life of HI at a pressure of 0.500 atm?
