The triprotic acid like H₃PO₄ contains three protons H⁺ so it ionized through three steps, the acidity strength of first proton higher than second proton higher than third one so Ka1 > Ka2 > Ka3 But
For pKa which equals to -log Ka ... the higher the value of Ka, the smaller the value of pKa. so the correct answer will be:
pKa1 < pKa2 < pKa3
Answer:
Synthesis
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
General equation;
A + B → AB
The given reaction is synthesis reaction.
Chemical equation:
2Al + Cl₂ → 2AlCl
it is also redox reaction because oxidation reduction take place.
The oxidation state of aluminium and chlorine is zero on left side while it on right side aluminium become cation with charge of +1 and chlorine become anion with a charge of -1.
Aluminium is reducing agent while chlorine is oxidizing agent.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.

Increasing the concentration would increase the rate of reaction. This is because there would be more particles.Therefore, there would be an increase in the rate of successful collisions per second. More successful collisions would mean that the reaction occurs much quicker.
