Polycrystalline copper has a steady$-$state creep rate of $1$E$-4/$s at $560$ degrees $C$ when subjected to a given tensile stress. The activation energy, Qc$,$ for creep in copper is $197k\frac{J}{m}ol.$ Calculate the steady$-$state creep rate of copper at $436$ degrees $C$ at a stress which is $63\%$ higher than the original. Use n$=5.$ Report your answer in $\%/$s$.$
