Please answer the last part only (Solving for [c}t. Please show all steps of integration to get to answer. Thank you!

(b) Consider a reversible, monovalent binding reaction between a ligand, L, and receptor, R, to form a complex, C: L+RC (b1) Consider the situation where there is negligible dissociation and write a mass balance for [C]. ( 2 points) (b2) Assume that the ligand is in excess, [L]0=[L], and express your new mass balance equation in terms of [C],[L]0, and [R]0 only ( 3 points). (b2) Solve for [C](t) assuming [C](0)=0. Note [L]0, and [R]0 are constants. (3 points)
