Which statements are true about reversible reactions?
umka21 [38]

Answer:

Reversible reactions exhibit the same reaction rate for forward and reverse reactions at equilibrium.

Reversible reactions exhibit constant concentrations of reactants and products at equilibrium

Explanation:

A reversible reaction is a reaction that can proceed in both forward and backward direction.

Equilibrium is attained in a chemical system when there is no observable change in the properties of the system.

At equilibrium, a reversible reaction is occurring in at same rate. That is, the forward and backward reaction is occurring at the same rate. As the rate of the forward and backward reaction remains the same, the concentrations of the reactants and products will also be the same in order for the equilibrium to be maintained.

The equilibrium constant Kc for the equation2H2(g) + CO(g) ⇌ CH3OH(g)is 35 at a certain temperature. If there are 3.21 ×10−2 mol
12345 [234]

Answer: the concentration of [CO]= 0.0532M

Explanation:

From The equation of reaction

2H2(g) + CO(g) ⇌ CH3OH(g)

Applying Kc= [CH3OH]/[H2]^2[[CO]

[CH3OH]= 0.00487

[CO]= x-0.00487

[H2]=(0.032-0.00487)^2=0.0271

Substitute into formula

Kc=[CH3OH]/[H2]^2[[CO]

35= 0.00487/(0.0271)^2(x-0.00487)

Simplify

x-0.00487=0.189

x= 0.00487+0.189=0.193moles

[CO]= n/C= 0.193/3.63= 0.0532M

Addition reactions of alkenes are characterized by _________. A) formation of a bond B) addition of two groups across a double b
mr_godi [17]

Answer:

B. ADDITION OF TWO GROUPS ACROSS A DOUBLE BOND

Explanation:

Addition reaction of alkenes involves the conversion of the double bond in alkenes Inyo single bonds by the addition of two groups of atoms or radicals.

During this addition reaction, two substances, an unsaturated compound(e.g. ethane) and an attacking reagent (hydrogen, halogens, hydrogen halides, chlorine and bromine water) combines to form a single new compound without forming any other products. So a saturated product or one in which is an increase in degree of saturation is formed.
