Does the amount of methanol increase, decrease, or remain the same when an equilibrium mixture of reactants and products is subj
denis23 [38]

Answer:

a. Methanol remains the same

b. Methanol decreases

c. Methanol increases

d. Methanol remains the same

e. Methanol increases

Explanation:

Methanol is produced by the reaction of carbon monoxide and hydrogen in the presence of a catalyst as follows; 2H2+CO→CH3OH.

a) The presence or absence of a catalyst makes no difference on the equilibrium position of the system hence the methanol remains constant.

b) The amount of methanol decreases because the equilibrium position shifts towards the left and more reactants are formed since the reaction is exothermic.

c) If the volume is decreased, there will be more methanol in the system because the equilibrium position will shift towards the right hand side.

d) Addition of helium gas has no effect on the equilibrium position since it does not participate in the reaction system.

e) if more CO is added the amount of methanol increases since the equilibrium position will shift towards the right hand side.

What is the temperature at which something boils? A chemical change or property or a physical change or property?
DerKrebs [107]
The boiling point of a substance is a physical property. A physical property of a material or substance is one that can be observed without changing or altering the composition of the material. Examples are mass, Density, Color, solubility, boiling point, melting point . A chemical property of a substance is one that describes how the material changes into a completely different substance and is observed only during a chemical reaction. Examples of chemical properties include types of chemical bonds, heat of combustion, reactivity with other metals, oxidation state and enthalpy of formation.
