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.
<span>The average speed of the gas is related to the kinetic
energy of the gas. The kinetic energy of
the gas is also related to the temperature of the gas. If the average speed of
the gas is closer to zero, it means that it has very low motion or kinetic
energy. This can be inferred that the gas has a very low temperature. At absolute
zero, the motion of all the gas molecules stops. This means that the kinetic
energy of the gas is also zero. Zero kinetic energy means zero average speed.</span>
<span>So, the answer is cylinder B. The average speed of the gas
in cylinder B is closest to zero.</span>
Ok, after doing an immense amount of research I came up with the most logical answer.
A. Is indicated by a negative enthrall sign.
Reasoning: an endothermic reaction is ice melting and the energy being more than its surroundings. Not specified to ice but as an example, ice is endothermic. That puts d and b out of the running leaving you left with a and c.
When I searched up enthalpy, it said “When a substance changes at constant pressure, enthalpy tells how much heat and work was added or removed from the substance.” Which is similar to c, right? Yeah, meaning both a and c are similar in that aspect.
The reason I decided to go with a is because heat is NOT released into the surrounding, exothermic reactions release energy and heat into the surrounding.
Lipids are in a class called fat or lipid solvents.
