The thermal decomposition of ethylene occurs in many industrial contexts: during ethylene transit in pipelines, formation of polyethylene, drying of the gas, and separating it from impurities. The decomposition reaction is as follows:
CH2-CH2() → CH4(g) + C(graphite)
If the decomposition of 1 mole of ethylene with a gas density of 0.215 g/mL starts at 12°C and the temperature increases by 950 K, what is the final pressure of the confined gas? (Ignore the volume of graphite and use the van der Waals equation.)
A 2.0 L-reaction flask initially contains 0.17 mol CO, 0.15 mol H2, and 0.10 mol CH3OH (methanol). If this mixture is brought in contact with a zinc oxide-chromium(III) oxide catalyst, the equilibrium shown below is attained.
Question- If the cost of both of the alcohol and carboxylic acid were prohibitive, how would you maximize the yiled of your Fisher esterification product while keeping the cost down

A sample of hard water contains about 2.0x10-3MCa2+. A soluble fluoride-containing salt such as NaF is added to "fluoridate" the water. What is the maximum concentration of F- that can be present without precipitation CaF2? Ksp of CaF2=5.3x10^-11.
Give the basicity order? List from most to least basic. 3. Explain the basicity order in terms of resonance and inductive (polar) effects and solvation effects.
Question- We considered mixing a strong base with a weak acid, but we did not consider mixing a strong acid with a weak acid. Consider mixing 0.1M HNO3and 0.1M HNO2. Predict the pH of the solution and the percent ionization of the nitrous acid. Ra..
