The decomposition of N205 in CCI4 is a first-order reaction. If 2.56 mg of N2Os

Question

The decomposition of N205 in CCI4 is a first-order reaction. If 2.56 mg of N2Os is present initially, and 2.50 mg is present after 4.26 min at 55 degreeC, what is the value of the rate constant, k? Enter a response and then click Submit. Identify the concentration-time equation for a first order reaction. Calculate the ratio of the concentration after and before reaction. Take the natural log of this ratio. Using the natural log of the ratio of concentrations and the time elapsed, calculate the rate constant.

Explanation / Answer

K*t=-ln(C0/C)

K=ln(2.56/2.5)/4.26

K=5.567*10-3min-1
