In an attempt to identify whether or not folding intermediates are in the protein solution, the viscosity of the solution is measured at t=310k and t=340k. again, at t=310k fd=0.200 and for the folding intermediate fx=0.200. similarly at t=340k fd=0.800 and fx=0.100 . however, for the viscosity measurements dx=0.400. from your values of kapp at t=310k and t=340k, calculate the apparent molar enthalpy of folding δ
