The Consecutive, second order, irreversible reactions are carried out in a batch reactor A +S rightarrow^k_1 X X + S rightarrow^k_2 Y If one mole of A and two moles of S are initially added. Find no. Of moles of X after half the A is consumed, given k_2/k_1 = 2. Physical Information: Rate Equations dC_A/dt = -k_1 C_A C_S dC_X/dt = k_1 C_A C_S - k_2 C_X C_S

Saline iv fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. a new supplier sells 500 ml bags for $2 each. the hospital uses about 10,000, 1000 ml bags each month. nurses report that about half of the bags are more than half full when they are discarded. if you are going to use only one supplier, which size bag provides the best deal, and how much will you save each month? compare the cost of the new supplier to the current one.
