Question

Chlorine oxide (ClO), which plays an important role in the depletion of ozone, decays rapidly according to the equation 2ClO(g) → Cl2(g) + O2(g) From the following data, determine the reaction order and calculate the rate constant of the reaction. Time (s) [ClO] (M) 4.26 × 10−3 7.73 × 10−6 4.88 × 10−3 6.27 × 10−6 5.50 × 10−3 5.28 × 10−6 6.12 × 10−3 4.56 × 10−6 6.74 × 10−3 4.01 × 10−6

Answer 1

Answer:

It is a zero order reaction and k=0.005M/s

Explanation:

Once you plot the graph, you can see it is a linear equation which decays. This is common to zero order reaction which are given by the following equation: C=Co-kt. The equation given by the graph is C=1x10-5 - 0.0015t. Therefore, the slope = -K
