[C] t(s) 0 1.000000 100 0.778801 200 0.606531 300 0.472367 400 0.367879 500 0.286505 600 0.223130 800 0.135335 1000 0.082085 1200 0.049787 The process is governed by the rate law given by the equation: = In (SO3)-kt+In (SO3)-0 Where k is the rate constant and t is the time, and In is natural logarithm. By calculating the corresponding values of In[SO3] and plotting the graph of In [SO3] against time, t, determine the rate constant k of the reaction.
