If someone can solve it in excel and explain how to do it please: Porphyridium cruentum is placed in a $0\mathrm{.}6$ L batch bead mill. The mill uses $1$ mm diameter beads and rotatres at a speed of $360$ rpm$.$ The total protein concentration and the BFE protein concentration are determined with respect to the operation time.

Calculate the protein release constant

Calculate the BFE release constant

Calculate the time at wich $80\%,90\%$ and $95\%$ bfre release is achieved
