For the isomerization of n-butane to isobutene we have G= -RT LnK where R= 1.9872 and K= (isobutene)/(n-butane) The temperature dependent Gibbs free energy (in calories) for isobutene and nbutane are given by G= -31450 - 70.42 T and G= -29810- 74.
Determine Radial and tangential stresses as functions of r. Calculate these stresses at a minimum of 7 radial positions and plot your results.
