Answer:

A reversible reaction is a reaction that occurs in the forward and backward directions.  If the reaction were in equilibrium, the rate of the direct reaction would be equal to that of the reverse reaction.

Explanation:

A reversible reaction is one that moves in both directions simultaneously.

We have to:

Direct reaction: aA + bB → cC + dD

Reverse reaction: cC + dD → aA + bB

So we can represent this type of reaction in a single form:

aA + bB ↔ cC + dD

The double arrow (↔) is an indication that a process is reversible, with the arrow to the right (→) corresponding to the direct reaction, while the arrow to the left (←) corresponds to the reverse reaction. If these two arrows are of different sizes, this means that the speed with which they are processed is different, and the larger the arrow, the greater the speed of the reaction. On the other hand, if they are exactly the same size, it means that the system has reached chemical equilibrium, where the rate of development of the direct reaction is equal to the rate of development of the reverse reaction.

In summary, we can say that a reversible reaction is a reaction that occurs in the forward and backward directions. If the reaction were in equilibrium, the rate of the direct reaction would be equal to that of the reverse reaction.

A reversible reaction is a reaction that takes place in the ( formation of reactants to products and products to reactants simultaneously ). If the reaction were to ( be in dynamic equilibrium ), the rate of forward reaction would be equal to that of the reverse reaction.

hope this helps :))

The formation constant for the reaction ag (aq) 2nh3(aq) ag(nh3)2 (aq) is kf = 1.7 × 107 at 25°c. what is δg° at this temperatur
anzhelika [568]

The value of ΔG° at this temperature is -18034.18 J/mol

Calculation,

Given information

formation constant (Kf)= 1.7 × 10^{7}

Universal gas constant (R) = 8.314 J/K• mol

Temperature = 25° C = 25 °C + 273 = 300 K

Formula used:

ΔG° = -RT㏑Kf

By putting the valur of R,T, Kf we get the value of ΔG°

ΔG° = - 8.314 J/K• mol×300K㏑ 1.7 × 10^{7}

ΔG° = -2494.2㏑ 1.7 × 10^{7} = -18034.18 J/mol

So, change in standard Gibbs's free energy is -18034.18 J/mol

Calculate the acid dissociation constant Ka of a 0.2 M solution of weak acid that is 0.1% ionized is ________.
mars1129 [50]

Answer: acid dissociation constant Ka= 2.00×10^-7

Explanation:

For the reaction

HA + H20. ----> H3O+ A-

Initially: C. 0. 0

After : C-Cx. Cx. Cx

Ka= [H3O+][A-]/[HA]

Ka= Cx × Cx/C-Cx

Ka= C²X²/C(1-x)

Ka= Cx²/1-x

Where x is degree of dissociation = 0.1% = 0.001 and c is the concentration =0.2

Ka= 0.2(0.001²)/(1-0.001)

Ka= 2.00×10^-7

Therefore the dissociation constant is

2.00×10^-7

Calculate the standard cell potential given the following standard reduction potentials: Al3++3e−→Al;E∘=−1.66 V Cu2++2e−→Cu;E∘=0
Maru [420]

Answer:

Explanation:

To calculate the cell potential we use the relation:

Eº cell = Eº oxidation + Eº reduction

Now in order to determine which of the species is going to be oxidized, we have to remember that the more the value of the reduction potential is negative,  the greater its tendency to be oxidized is. In electrochemistry we use the values of the reductions potential in the tables for simplicity  because the only thing we need to do is change the sign of the reduction potential for the oxized species .

So the species that is going to be oxidized is the Aluminium, and therefore:

Eº cell = -( -1.66 V ) + 0.340 V =  5.06 V

Equally valid is to write the equation as:

Eº cell = Eº reduction for the reduced species - Eº reduction for the oxidized species

These two expressions are equivalent, choose the one you fell more comfortable but be careful with the signs.
