Question
1. Chemical reactions progress towards equilibrium. What do we call organisms that have reached equilibrium for all their chemical reactions.
2. Which type of biofuel do you believe is the ruel of the future? state three reasons to support your claim. What is one negative aspect of your choice of fuel.
3. Entropy is the measure of disorder in a system.
a) which form of H2O has the most entropy out of (1) steam, (2) water, or (3) ice? Why?
b) Which form of traffic has the most entropy, (1) a large pile up accident, (2) a large traffic jam during rush hour, or (3) several cars in a full parking garage. Why?
Explanation / Answer
1. When a chemical reaction takes place within an organism which prevents the entry or escape of any of the substances involved in the reactions, the quantities of the reactant components change as some are consumed and others are formed. Eventually at one point this change will come to an end, after which the composition will remain unchanged as long as the system remains undisturbed. The system is then said to be in its equilibrium state, or more simply, "at equilibrium". the organismis said to be in chemical equilibrium
2.A few years ago, everybody talked about biofuels and it's benefits. Scientists were particularly enamored with corn ethanol, seeing it as a path to "energy independence" while greener folks preferred biodiesel made from waste cooking oil (still a great choice, but it doesn't scale up and can be problematic with newer diesel engines). Fans of biofuels said that these were supposed to be just a bridge to second-generation biofuels like cellulosic ethanol and algae biodiesel; these wouldn't be made from food crops or limited feedstocks, and they would be much greener overall. but one drawback is that plants nedd to be cut to extract this this in turn leads to less greenery around.
3.a, 1.steam
b. 2. a large traffic jam during rush hour- as all the drivers are going to work there will be maximum commuters on the road and on top of it if there is a jam it means pooling of all the vehicles that including the time when there is maximum traffic.
That was a good vision, but somewhere along the way, the dream seems to have fizzled out. Many are still working on making it happen, but most next-gen biofuel projects seem to have been cancelled or scaled back, and 40% of America's corn production is still going to ethanol production, raising food prices for everyone and using fertile arable land to make fuel that isn't that much greener than what it replaces
