The question is incomplete, here is the complete question:
Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas:
A gas vessel is charged with a mixture of 
and 
, which is allowed to equilibriate at 450 K. At equilibrium the partial pressures of the three gases are 
= 0.126 atm , 
= 0.156 atm , and 
= 1.60 atm. What is the value of 
at this temperature?

Hence, the for the given reaction is 81.4
Answer:
The strong acids are fully ionized in aqueous solution, and they contains higher concentration of hydrogen ions. Strong acids are lower pH in nature. Some examples of strong acids are:
1) Hydrochloric acid.
2) Nitric acid.
3) Sulfuric acid.
The weak acids are not fully ionized, means they are partially ionized in aqueous solution, and they contains lower concentration of hydrogen ions. Weak acids are higher pH in nature than strong acid. Some examples of weak acids are:
1) Ethanoic acid.
2) Acetic acid.
3) Nitrous acid.
Answer:
A
Explanation:
In a galvanic cell, energy is produced by spontaneous chemical processes.
The cathode and anode of this cell will depend on the relative position of the two metals in the electrochemical series.
Aluminium is higher in the electrochemical series so aluminium will be the anode. Silver is lower in the electrochemical series so silver will be the cathode.
Recall that oxidation (electron loss) occurs at the anode while reduction (electron gain) occurs at the cathode.
Answer: Enzymes speed up the reaction rate.
Enzymes are regenerated when the reaction is completed.
Enzymes affect the reaction pathway by forming an enzyme-substrate complex.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Enzymes are biocatalysts and are highly specific in their action. The specificity of enzymes is due to the presence of some specific regions called as active sites. These active sites form weak bonds with substrate molecules.
The specific binding leads to formation of an enzyme substrate complex which accounts for high specificity of enzyme catalyzed reactions.
Once a proper orientation is achieved, substrate molecules react to form products and products leave the enzyme surface as they do not have any affinity towards the enzyme site and are regenerated at the end.
Enzymes work best in optimum temperature and pH range.The enzyme gets denaturated at high pH and temperature.
