Can someon please help me solve this problem step by step?

Q$2)$ A plate column will be designed to rectify a binary mixture. The feed which is a mixture of liquid and vapor will be introduced to the column at a flow rate of $85$kmo$\frac{l}{h}.$ It contains $35$mole$\%$ light key component at the feed and the $q$ value is $0\mathrm{.}62.$ If the fractional recovery of the light key component is $97\%$ and the mole fraction of light key in the distillate stream is $0\mathrm{.}96,$ calculate:

a$)$ Total number of theoretical stages and the optimum location of the feed tray

b$)R_{\text{m}\text{i}\text{n}}$

c$)$ Condenser and reboiler loads

$($Note: Use Below Figure, $R={1\mathrm{.}3}^{\text{'}}{R}_{\text{m}\text{i}\text{n}},$ take average latent heat as ${10}^{4}k\frac{J}{m}ol)$
