Under what conditions does an increase in temperature turn a nonspontaneous process into a spontaneous process?

Chemistry
1 answer:
Ymorist [56]3 years ago
4 0

Answer:ΔH < 0, ΔS > 0

Explanation:

Consider ∆G= ∆H-T∆S

If ∆H is negative and and ∆S is positive, when T is increased, T∆S becomes more positive until the result of the difference between ∆H-T∆S becomes negative. Remember that a reaction is only spontaneous when ∆G is negative. Hence under these conditions, ∆G becomes negative and the reaction becomes spontaneous.

What carboxylic acid would be formed if the malonic ester synthesis (alkylation of diethyl malonate followed by hydrolysis with
uranmaximum [27]

Answer:

cyclohexilic acid

Explanation:

The malonic ester synthesis is often used to form different types of carboxilic acid. In this case, we have excess of base, so we can expect a ring formed in the molecule.

In the first step, the base substract the more acidic hydrogen of the ester. In the next step we have the ester reacting with the dibromopentane. Then, in the next step, the excess of base will substract again the acidic hydrogen remaining of the carbon, and then, will promove a Sn2 reaction with the bromine in the pentane (That it was previously attached to the molecule). In this step, a ring id formed. Then, the hydrolisis with acid, will form carboxilic acid in both sides of the molecule, and finally the decarboxilation in heat will separate the molecule and formed the cyclohexilic acid.

The picture below shows the mechanism

In the following chemical reaction, which element is shown to be violating the law of conservation of mass? C3H8 + 4O2 -&gt; 3CO
AlexFokin [52]
Checking if it is balanced:

C             
3               3

H
8                  4*2 = 8

O
8                  3*2   + 4 = 6 + 4 = 10
8                   10

Only O is not balanced.

So O is violating the law.     Option C.
