Question

The data is below and am only asking for the second portion (finite differnce approximation to find reaction order, aplha, and rate constant. If you would like to do the first portion then please do. I'm working on it now myself.

Question: Find (dP/dt) using (a) interpolating polynomial fit (in Excel) and (b) finite difference approximations, and use these values to calculate the reaction order , alpha, and rate constant, k using an appropriate relationship between (dP/dt) and P.

Time (min):
0, 2.5, 5, 10, 15, 20

Total Pressure (mmhg):
7.5, 10.5, 12.5, 15.8, 17.9, 19.4
