1. For the following decomposition process, A - products, given [A] versus time data. Describe how you would graphically determine if it is zero order, or a second order process with respect to "A" ?3. The following initial rates were measured for the thermal decomposition of azomethane: CH3NNCH3(8) C2H6(8) + N2(8) Initial Initial Rate Experiment [CH;NNCH3(g)] (M/s) 0.26 4.0 x 10-2 0.13 1.0 x 10-2 a) Determine the rate law for the decomposition process. b) Determine the rate constant, k, for the process.7. There are three stages involve in waste decomposition in a landfill, which are aerobic, facultative and anaerobic decomposition. Evaluate the mechanism of reactions happened in each stage which producing methane and carbon dioxide gases at the end of the decomposition process
