Given the following data, what is the order of the reaction? How long will it take for the half of the trans compound to decompose?
I think you are to graph these data and determine the slope of the line. I don't know what you can't calculate k from each 10 minute increment and see if k agrees, and assume a 1st order reaction from that. Or you can calculate k form
ln(No/N) = kt from the data and see if k is contant for this first order equation. If it is, then t(1/2) = 0.693/k.
