The equilibrium constant (Kc) is the product of the equilibrium concentrations of the products raised to their corresponding stoichiometric coefficients divided by the reactants as well. In this case the equilibrium concentration of Cl2 which also applies to SO2 is 1.3x10^-2. The final equilibrium concentration of SO2Cl2 is 9x10^-3. Kc is then equal to 0.0188.

Answer : The the value of equilibrium constant is, 1.87\times 10^{-2}

Solution : Given,

Concentration of SO_2Cl_2 = 2.2\times 10^{-2}M

Concentration of Cl_2 = 1.3\times 10^{-2}M

The given balanced equilibrium reaction is,

                     SO_2Cl_2(g)\rightleftharpoons SO_2(g)+Cl_2(g)

Initially          2.2\times 10^{-2}M        0        0

At eqm,

The concentration of SO_2Cl_2 = (2.2\times 10^{-2}-1.3\times 10^{-2})M=0.9\times 10^{-2}M

The concentration of Cl_2 = 1.3\times 10^{-2}M

The concentration of SO_2 = 1.3\times 10^{-2}M

The expression for equilibrium constant will be,

K_c=\frac{[SO_2]\times [Cl_2]}{[SO_2Cl_2]}

Now put all the given values in this formula, we get

K_c=\frac{(1.3\times 10^{-2})\times (1.3\times 10^{-2})}{(0.9\times 10^{-2})}

K_c=1.87\times 10^{-2}

Therefore, the value of equilibrium constant is, 1.87\times 10^{-2}

For changing potential energy; When you drop a book, gravitational potential energy is transformed into kinetic energy. Your car transforms the chemical potential energy stored in gasoline into the kinetic energy of the car's motion.

For Kinetic Energy; kinetic energy can be converted into electrical energy by a generator or into thermal energy by the brakes on a car.

choli [55]
The least electronegative component in the electron transport chain is the Hydrogen ion. 
The more electronegative is NAD+
The other component is H2O,
Next are the energy carrier molecules which are the ADP and ATP
And finally, the most electronegative is O2.

What are the observable indicators that can be evidence a chemical change might have occurred?
kozerog [31]

solution:

The four observations that indicate a chemical change are:  

1) Precipitate is formed  

2) Odour  

3) Heat is emitted ( change in temperature)  

4)Formation of a Gas

Changes of state may of course be merely physical—as for example when liquid water is boiled to form a vapor. (These and other examples of physical changes resulting from temperature changes are discussed in the essays on Properties of Matter; Temperature and Heat.) The vapor produced by boiling water, as noted above, is still water; on the other hand, when liquid water is turned into the elemental gases hydrogen and oxygen, a more profound change has occurred.  

Likewise the addition of liquid potassium chromate (K2CrO4) to a solution of barium nitrate (Ba[NO3]2 forms solid barium chromate (BaCrO4). In the reaction described, a solution is also formed, but the fact remains that the mixture of two solids has resulted in the formation of a solid in a different solution. Again, this is a far more complex phenomenon than the mere freezing of water to form ice: here the fundamental properties of the materials involved have changed.  

The physical change of water to ice or steam, of course, involves changes in temperature; likewise, chemical changes are often accompanied by changes in temperature, the crucial difference being that these changes are the result of alterations in the chemical properties of the substances involved. Such is the case, for instance, when wood burns in the presence of oxygen: once wood is turned to ash, it has become an entirely different mixture than it was before. Obviously, the ashes cannot be simply frozen to turn them back into wood again. This is an example of an irreversible chemical reaction.  

Chemical reactions may also involve changes in color. In specific proportions and under the right conditions, carbon—which is black—can be combined with colorless hydrogen and oxygen to produce white sugar. This suggests another kind of change: a change in taste. (Of course, not every product of a chemical reaction should be tasted—some of the compounds produced may be toxic, or at the very least, extremely unpleasant to the taste buds.) Smell, too, can change. Sulfur is odorless in its elemental form, but when combined with hydrogen to form hydrogen sulfide (H2S), it becomes an evil-smelling, highly toxic gas.
