Numerical value of rate constant for gaseous reaction

Question

Assignment:

Question 1. The numerical value of the rate constant for the gaseous reaction

2N₂O₅ reacts to form 4NO₂ + O₂

was found to be 5.80 times 10 exp -4. The initial concentration of N2O5 was 1.00 mol/L. Assuming all measurements are recorded in seconds, determine the time required for the reaction to be 60% complete.

Question 2. Reaction between chloroform and chlorine

step 1: Cl₂--- 2Cl Fast

step 2: CHCl₃ + Cl ------ CCl₃ + HCl slow

step 3: CCl₃ + Cl ------- CCl₄ fast

If this is the correct mechanism what would be the experimental rate law

Question 3. At 25 degrees Celsius, the equilibrium partial pressures in the reaction

NOCL(g) equlibrium NO(g) + 1/2 Cl₂

PNOCl = 1.3 atm, PNO 0.050 atm PCl₂ = 0.36 atm

What is Kp for this reaction.

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