Please answer the question fully and please give the correct letter for the answer to this problem and explain

D Question 1 50 pts Similar to the problem described in the video, here we have the same elementary gas reaction 4A + 2B 2C. Here, the feed is also an equal molar gaseous mixture of A and B, entering at a concentration of 1 mol/L each. As before, the final conversion of Ais 25 %. The reaction is carried out at constant temperature, but in this case, there is pressure drop across the reactor, making the pressure at the outlet to be 65 % of that at the inlet. What would the concentration of A be in this case? (a) 0.071 (b) 0.125 (c) 0.556 (d) 0.856 la) (b) (c) (d) d 50 pts Question 2
