Question # 1

The characteristics of reversible reactions are the following except:

Choose an answer

Products never recombine to form reactants.

They never complete

The proced in both ways

They have a double arrow between reactants and products.

If Qc = Kc the reaction goes in:

Choose an answer

Forward

Reverse

At equilibrium state

None

when a system is in equilibrium state or in dynamic equilibrium state.

Choose an answer

Reactants and product are equal

Forward reactions stops

Reverse reactions stops

Forward reaction rate and reverse reaction rate

Formation profess of Ammonia by the combination Hydrogen and Nitrogen was given by:

Choose an answer

Dalton

Thomson

Haber

Waage

At dynamic equilibrium state:

Choose an answer

Rate of forward reaction≠ Rate of reverse reaction

Rate of forward reaction > Rate of reverse reaction

Rate of forward reaction = Rate of reverse reaction

Rate of forward reaction < rate of reverse reaction

When the magnitude of Kc is very small it indicates.

Choose an answer

Equilibrium will never establish

All reactants will be converted to products.

Reaction will go to completion

The amount of products is negligible

In chemical reaction , the substances that combine are called.

Choose an answer

Reactants

Products

Equlibrium

Numerator

Which type of reactions take place in both directions?

Choose an answer

Addition reactions

Reversible reactions

Irreversibel reactions

In irreversible reaction, dynamic equilibrium:

Choose an answer

Never establishes

Establishes before the completion of reaction

Establishes after the completion of reaction

Establishes readily

The value of K_c depends on.

Choose an answer

Temperature

Pressure

Volume

Atmosphere

If Qc > Kc the reaction will be in

Choose an answer
