In the absorption of ammonia into water from an air-ammonia mixture at $300 \mathrm{~K}$ and $1 \mathrm{~atm}$, the individual film coefficients were estimated to be $k_{L}=6.3 \mathrm{~cm} / \mathrm{h}$ and $k_{G}=1.17 \mathrm{kmol} / \mathrm{m}^{2} \cdot \mathrm{h} \cdot \mathrm{atm}$. The equilibrium relationship for very dilute solutions of ammonia in water at $300 \mathrm{~K}$ and $1 \mathrm{~atm}$ is $y_{A, i}=1.64 x_{A, i}$. Determine the following:

(a) $k_{y}$

(b) $k_{x}$

(c) $K_{y}$

(d) Fraction of the total resistance to mass transfer that resides in the gasphase.
