After a 680 hour heat treatment at 1130°c the concentration of a is 2.9 wt% at the 3.4 mm position within metal b. at what temperature (in kelvin) must the diffusion couple need to be heated to produce this same concentration at a 1.8 mm position after 680 h? the preexponential and activation energy values for the diffusion of a in b are 2.7 × 10-5 m2/s and 257 kj/mol, respectively.

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
