An irreversible reaction occurs in a continuously stirred tank reactor as shown by the equation below. Assuming that the feed only contains of $A.$

$2AB$

Derive the transfer function that shows the change in outlet concentration $C_A$ to the feed stream concentration.

Hint $1.$ do component balances for A only.

Hint $2.$ Your transfer function should be in the form of

$C_{A2}^{**}(s)=\frac{K}{S+1}{C}_{A1}^{**}(s)$
