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
