Problem 14.30

Species $$\mathrm{N}_{2} \mathrm{O}_{4} \text { and } \mathrm{NO}_{2}$$ as gases come to equilibrium by the reaction: $$\mathrm{N}_{2} \mathrm{O}_{4} \rightarrow 2 \mathrm{NO}_{2}$$.

(a) For T = 350 K and P = 5 bar, calculate the mole fractions of these species in the equilibrium mixture. Assume ideal gases.

(b) If an equilibrium mixture of $$\mathrm{N}_{2} \mathrm{O}_{4} \text { and } \mathrm{NO}_{2}$$ at conditions of part (a) flows through a throttle valve to a pressure of 1 bar and through a heat exchanger that restores its initial temperature, how much heat is exchanged, assuming chemical equilibrium is again attained in the final state? Base the answer on an amount of mixture equivalent to 1 mol of $$\mathrm{N}_{2} \mathrm{O}_{4}$$, i.e., as though the $$\mathrm{NO}_{2}$$ were present as $$\mathrm{N}_{2} \mathrm{O}_{4}$$.

ENGR 301, Gerard Gouw Canadian forms of business organizations Sole proprietorship: Is an individual carrying a business under his/her name The individual owns and operates the business The assets of the organization are owned by the individual and ae considered as being part of the individuals personal worth  Any profits made by the business belong to the individuals  Any losses borne by the business are losses that are borne by the individual No separation between the individual’s personal assets and those of the business Advantages of Sole Proprietorship  Easy and inexpensive  Relatively low cost of start up  Lowest amount of regulatory burden Disadvantages  Unlimited liability  Business’s income is taxed as personal income  Lack of continuity for business if owner needs to be absent  Difficult to raise capital because of insufficient personal assets to act as collateral. Partnership Formed when two or more individuals usually from the same profession decide to forma business together Reason for forming a business partnership  Divide risks  Combine management and financial resources Formation of business partnerships is governed by provisional partnership acts  A partnership agreement must be established Limited liability partnership  A variation of the partnership form of business organization Liability of a limited partner is for debts to a specified extent only Limited partners contribute money or other tangible assets towards the capitalization of the business Advantages of
