Question

4) If the reaction SO₂Cl₂ → SO₂ + Cl₂ is first-order reaction. At 230^oC, k = 0.125 hr^-1.

If the initial concentration of SO₂Cl₂ is 0.250 M, what is the concentration after 7.6 hours?
How long will it take for the concentration of SO₂Cl₂ to drop to 0.0651 M?
What is the half-life for this first order reaction?

Answer 1

Answer #1

A. ln(A°/A) = rate constant * time

= ln ( 0.250 / A) = 0.125 * 7.6

A = 0.0967 M

B. ln ( 0.250 / 0.0651) = 0.125 * time

= 10.763 hr

C. T(1/2) = 0.693 / rate constant

= 0.693 / 0.125

= 5.544 hr
