What is the value of DeltaG in a spontaneous reaction

krok68 [10]

Gibbs free energy of a reaction ( Δ G ) is the change in free energy of a system that undergoes the chemical reaction. It is the energy associated with the reaction, which is available to do some useful work. If ΔG<0 , then the reaction can be utilized to do some useful work. If ΔG>0 , then work has to be done on the system or external energy is required to make the reaction happen. ΔG=0 when the reaction is at equilibrium and there is no net change taking place in the system.

A pool owner adds a compound containing chlorine to the pool to disinfect it. However, too much of the compound is added. As a r

MrMuchimi

Answer: He could add a base to the pool to neutralize the acid.

Explanation:

Chlorine is used to disinfect the pools as it produces hypochlorous acid in water. This hypochlorous acid is unstable and gives hydrochloric acid and nascent oxygen which is used to disinfect.

$Cl_2+H_2O\rightarrow HOCl$

$HOCl\rightarrow HCl+O$

The excess acid is neutralized by adding base which produces salt and water and thus decrease the acidity.

$Acid+Base\rightarrow Salt+water$

Adding more acid would increase the acidity further.

In a reaction at equilibrium, the partial pressure of SO2 is 137 torr and that of CL2 is 285 torr. What is the partial pressure

ElenaW [278]

Answer:

422 torr

Explanation:

According to Dalton's law of partial pressure, the total pressure exerted by a mixture of gases is the sum of their individual/partial pressure. Mathematically, this can be expressed as:

$P_{total} = P_{1} + P_{2} + ........+ P_{n}$

In this case, $P_{SO2}$ = 137 torr, $P_{Cl2}$ = 285 torr, hence

$P_{SO2Cl2}$ = $P_{SO2} + P_{Cl2}$

= 137 + 285

= 422 torr

The partial pressure of SO2Cl2 in this mixture is 422 torr.
