Rate constant for oxidation of ethanol

Question

Assignment:

Question 1. Ozone decomposes to oxygen according to the balance chemical equation below:

2O₃ → 3O₂

If the rate of disappearance of the ozone is -7.2E-4 M/s, what is the rate of formation of oxygen?

Question 2. If 100kJ of heat is added to 54.0 g of water at 100°C, what is the final state of the water? MW H2O = 17.9 g/mole

Question  3. How many grams of NaCl do you need to add to 5.00 kg of water to make a solution that freezes at -10.0°C (assume an ideal solution)? MW NaCl = 58.4 g/mole

Question 4. If an individual records a blood alcohol level of 0.0267M (0.16% by volume), what will this person's blood alcohol level be 4 hours later if the rate constant for the oxidation of ethanol in the liver is 0.00425 M/hour?

Question 5. The reaction of NO and O₂ produces NO₂

2NO(g) + O₂(g) → 2 NO₂(g)

The rate constant is second order with respect to NO(g) and first order with respect to O₂(g). At a given temperature, the rate constant, k, equals 6.1E3 M-2S-1. What is the rate of reaction when the initial concentrations of NO and O₂ are 0.020 M and 0.015 M respectively?

Provide complete and step by step solution for the question and show calculations and use formulas.
