(a)Use an excel spreadsheet with the data provided
activity time (sec)
(b) Use the excel spreadsheet again with the data to prepare a graph of ln(activity) vs. time (seconds) . Use lin fit to produce the best straight line through the graph through the points and have the equation of that line printed on the graph.
ln (activity)t= _________t+_____________
Use the y-intercept of the line to calculate the activity which was present at the original time t=0
Use the slope of the line to determine the value of the rate of constant or decay constant
Use the equation to calculate the time at which the activity has decreased to 500
