Given a synthesis reaction involving the conversion of compound A to compound B using catalyst C, with reagent purities of 95% for A, 98% for B, and 99% for C, and reaction conditions of 100°C and 5 atm, predict the theoretical yield of compound B if the reaction is run for 2 hours, assuming a first-order reaction kinetics and considering the potential impact of common impurities such as water and oxygen on the catalyst activity. Provide a detailed breakdown of the calculation steps and assumptions made.

Design a factorial experiment to investigate the effects of pH and substrate concentration on the activity of enzyme X, with the goal of optimizing the reaction conditions for maximum yield. Assume a range of pH from 6 to 9 and substrate concentrations from 1 to 10 mM, and provide a detailed description of the experimental design, including the number of replicates, randomization strategy, and data analysis plan. Also, generate a list of potential controls and reference compounds that could be used to validate the results.

Given a chemical process stream with a complex mixture of compounds, including solvents, reactants, and byproducts, use a combination of mass spectrometry and nuclear magnetic resonance spectroscopy data to identify potential contaminants that could be affecting the yield or purity of the final product. Assume a dataset of 1000 mass spectra and 500 NMR spectra, and provide a detailed description of the data analysis workflow, including peak assignment, spectral matching, and statistical analysis. Also, generate a list of potential contaminants and their corresponding concentrations, along with recommendations for further experimental validation.

Create a standard operating procedure (SOP) for the disposal of chemical waste in a laboratory setting, including procedures for segregation, labeling, and storage of waste containers, as well as guidelines for personal protective equipment and emergency response procedures. Assume a laboratory generating a variety of hazardous waste streams, including organic solvents, acids, and bases, and provide a detailed description of the SOP, including flowcharts, checklists, and training requirements. Also, generate a list of relevant regulatory requirements and industry standards that must be followed.
