Select the correct answer,
What is the AG for the following reaction at 25°C?
N204(8) 2N02(9)
Given:
N20409): AG= 98.28 kJ/mol
NO2(9): AG= 51.8 kJ/mol
OA 5.32 kJ/mol
OB. 10.64 kJ/mol
OC -5.32 kj/mol
OD. -10.64 kJ/mol

Choice A: .

Explanation:

The Gibbs Energy change in a reaction can be found from the Gibbs Energy of formation :

.

In this case,

.

Note that since there are two molecules on the product side of this reaction, the for

One way to interpret this equation is to think about what means.

Refer to the diagram attached. The value of a substance is the energy it takes to form one mole of it from its elements under the standard conditions.

In this case, the two are like vectors that points from the elements to the two substances. However, the problem is asking for , which is the dashed arrow that points from to . To find that value, invert (the arrow on the left-hand side) and add that to (the arrow on the right-hand side.) The resultant value would be the dashed arrow, which stands for . In other words, .

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
