Blocking temperature equation
WebAug 18, 2015 · In the general case of a polysized sample, a representative blocking temperature value T B can be estimated from ZFC-FC experiments as a way to determine the effective anisotropy constant. Webln (k)=ln (A)-\frac {E_ {a}} {RT} ln(k) = ln(A)− RT Ea Note that this equation is of the form y=mx+b y = mx +b , and creating a plot of ln (k) versus 1/ T will produce a straight line with the slope –Ea /R. Plot of ln (k) versus 1/T for the decomposition of nitrogen dioxide The slope of the line is equal to -Ea/R.
