Compute the half-life for the decomposition of CO2 which is first order with respect to CO2 at 1000 Kelvin with K=1.8x10-13 sec.
The decomposition of N2O to N2 and O2 is a first order reaction. At 730 degrees Celcius the half-life of the reaction is 3.58x10^3 min. If the initioal pressure of N2O is 2.10 atm at 730 degrees Celcius, calculate the total gas pressure after on h..
