Answer: Option (C) is the correct answer.

Explanation:

When energy is supplied to an electron then on absorption of energy it tends to move from a lower energy level to higher energy level.

And, when this electron moves from higher energy level to lower energy level then excess of energy absorbed by it is released in the form of visible light or radiation.

This emission of energy is also responsible for imparting color to a compound.

Thus, we can conclude that energy is released in the form of radiation occurs when an electron moves from a higher energy shell to a lower energy shell.

Predict the effect of the following changes in the reaction CO (g) + 2 H2 (g) <-> CH3OH (g) + energy.
Sophie [7]

Explanation:

  Equation of reaction:

             CO   + 2H₂    ⇒   CH₃OH   +   energy

a.  An increase in pressure:

A change in pressure affects only equilibrium involving a gas or gases. Le Chatelier's principle can be used to predict the direction of displacement.

An increase in pressure on an equilibrium system will shift the position of equilibrium to the side having smaller volume and vice-versa

       CO   + 2H₂    ⇒   CH₃OH   +   energy

          3 moles                  1 moles

An increase in pressure will favor the forward reaction to be favored.

b. Addition of H₂:

An in concentration of a specie favors the direction that uses up that specie and lowers its concentration.

Addition of hydrogen gas increases the concentration of amount of substances reacting.

To annul the effect of the reactant, more the product is given. The equilibrium shifts in the forward direction.

I'm very confused can someone help me please I would really appreciate it
sasho [114]
1. temperature is dependent
2. energy is independent
3. the graph looks like a line sloping upward
4. the line means that as energy increases the temperature also increases
5. a straight line would mean that as energy increases temperature remains constant
