can you please answer those two Q

1. Calculate the bottoms composition again analytically, but instead of assuming relative volatility (RV)=5, use the equilibrium curve given. (Note: You're required to solve the problem analytically, so use the equilibrium curve as needed, but not the Mc Cabe Thiele Method.) 2. According to your understanding, explain why the RV at the condenser is greater than that at the bottom (reboiler)? Would it make sense for it to be the opposite
