Answer:

The reaction is exothermic.   A net release of energy from the reacting

substances into the surroundings makes

this an exothermic reaction.   The equation shows that 891 kJ of energy

are released as a product.   The graph shows that the reactants have

greater potential energy than the products.

This means the difference in energy is

released to the surroundings.

Answer: Exothermic

Explanation: Looking at the graph, you see that the reaction started with more energy than it ended with, meaning it gave out its energy over the course of the reaction. This is also confirmed by the reaction equation, which shows the energy (891 kJ) on the right side of the equation.

Paul [167]
Solving this chemistry is a little bit hard because the question didn't give some important detailed. 
So first, there are a couple problems with your question. 
We will just need to know which direction will it proceed to reach equilibrium.
Your expression for Kc (and Qc ) for the reaction should be: 
Kc = [C] / [A] [B]^2 
You have not provided a value for Kc, so a value of Qc tells you absolutely nothing. Qc is only valuable in relation to a numerical value for Kc. If Qc = Kc, then the reaction is at equilibrium. If Q < K, the reaction will form more products to reach equilibrium, and if Q > Kc, the reaction will form more reactants.

A pure white crystalline compound was found to melt at 112.5-113.0oC when taken on a melting point apparatus, and on further hea
Sergeeva-Olga [200]

According to the question, the determined melting point of the compound is 112.5-113.0oC. When the solidified compound was retried, the melting point was found to be 133.6-154.5oC. This greater range higher than  112°C is caused by reusing samples leads to errors.

A pure sample is known by its sharp melting point. A pure sample does not melt over a large range. We can see this in the predetermined melting points of the pure sample(112.5-113.0oC).

However, reusing a sample introduces errors because the pure sample may become contaminated leading to a larger and higher range of melting point (133.6-154.5oC) which is far above  112°C.
