If someone can help me and explain how to do it in Excel please:

Porphyridium cruentum is placed in a $0\mathrm{.}6$ L batch bead mill.

The mill uses $1$ mm diameter beads and rotates at a speed of $360$ rpm

The total protein concentration and the BFE protein concentration are determined with respect to the operation time $($data is shown in the following table$).$

a$)$ Calculate the protein release constant.

b$)$ Calculate the BFE release constant.

c$)$ Calculate the time at which $80\%,90\%,$ and $95\%$ BFE release is achieved.
