A chemical reactor gives a fractional conversion of only 10% of the expensive limiting reactant in the feed stream. Assuming not

hing will improve the reactor’s performance, how would you design a process to make better use of the expensive reactant? What performance characteristics would you need for other process units? (b) A second reactor is available which gives 90% conversion but allows an irreversible, undesirable side reaction with only a 50% selectivity or the desired product versus the undesired product. For some cases, the 1st reactor would be better, while for others the 2nd reactor is a better choice. Explain what performance characteristics of other units would dictate this choice?

Answer:

Explanation:

A) install a SEPARATION unit on the output from the reactor and feed the unreacted reagents back to the reactor feed in a RECYCLE stream.

B) Even if one had a perfect separation unit, the 65% or reactant which went to undesirable side reaction is wasted. Recycle is not effective to help poor selectivity of the reactor.

1. If I am in charge of developing a tax system for my country, I will structure the tax rate in such a way that, the rich will pay a higher percentage of tax than the poor. This type of tax system is called progressive tax. The income tax for instance will be based on the amount of income that each person earns, thus, those earning higher incomes will pay more tax than those earning lower incomes. Thus, the rich will always pay the greater percentage of taxes.

a. To fund health programs.
b. To fund national defense and security programs.
c. To fund social security programs.
d. To pay interests on national debts.
e. To pay war veterans.
f. To fund educational program.

Giving the following information:

You have just made a $1,500 contribution to your retirement account. Assume you earn a rate of return of 8.7 percent and make no additional contributions.

To find the final value we need to use the following formula:

FV= PV*(1+i)^n

A) n= 25
