Answer:
- <u><em>The first statement is false: a.At equilibrium, equal amounts of products and reactants are present. ΔG° is a function of Keq.</em></u>
Explanation:
When one part of a statement is false, the whole statement is false.
At <em>equilibrium,</em> the amounts of products and reactants does not have to be equal.
At equlibrium the rates of the forward reaction and the reverse reaction must be equal.
An equilibrium reaction may be represented by:
That represents two reactions:
- Direct reaction: A + B → C + D (A and B yield C and D)
- Reverse reaction: A + B ← C + D (C and D yield A and B: note that the arrow goes from right to left)
So, it is when the direct and the forward rates are equal that there is not net change in the amounts of all the species and so the reaction is is equilibrium).
As per the other statement, both parts are true:
- When reactants become products, they do so through an intermediate transitrion state: when the reactants approach each other and collide with enough energy and appropiate position, the bonds start to break and the bonds of the products start to form. This is the transition state.
- Most biocatalysts are proteins: enzymes are simply proteins, with specific structures, that may accelerate or even deceralate biochemical reactions.
Question 1 in section B is physical
By using what they know to produce new and helpful products
Answer:
The liquid which ever releases the greatest number of particles will have the lowest freezing point.
A) pure H2O
B) Aqueous FeI3 (0.030m) releases 4X's = 0.120 mol/litre ions
C) aqueous glucose (0.050m) releases 0.050 moles/litre glucoes
D) aqueous NaI (0.030m) releases 2X's = 0.060 mol/ litre ions
E) aqueous CoI2 (0.030m) releases 3 X's = 0.090 mol/litre ions
The answer is
B) Aqueous FeI3 (0.030m)
Answer: It is important to conduct multiple trials so one can get the best results, additionally, multiple trials with result in minimal errors. Finally it is important to conduct multiple trials because it will show you the actual answer/solution/whatever. If you do something once their may of been a random unknown affect and you would of never knew because you only conducted the experiement once.
