14. Using a mass spectrometer, a sample of an ancient wooden object was found to have a ratio of 14C to 12C equal to 3.3×10 -13 as compared to a current biological sample, which has a ratio of 14C to ¹2C of 1.2×10 −12 (Given: t, is 5730 years) What is the age of the object? 15. For the reaction, 2 A(g) + B₂(g) → 2 AB(g) The rate law is; rate = k[A][B₂]³ At 22.0 °C, k = 1234 M-³s-1. What would be the rate of the reaction if the concentration of A is 0.100 M and concentration of B₂ is 0.125 M.
