Question

213) . Reaction giving most stable product is A. 2H2(g) + O2(g) 2H2001) AH = -285.5kJ/mol B. C(s) + O2(g) CO2(g) AH = -393.5kJ/mol C. PC151g) PC13(g) + Cl2(g) AH = +84.2kJ/mol 2NH3 AH = -46.23kJ/mol D. N2(g) + 3H2(g)​

Answer 1

Answer:

Explanation:

Ig B, Cause it is releasing most amount of energy

Answer 2

The Reaction giving the most stable product is C(s) + O2(g) ----> CO2(g) ∆H = -393.5kJ/mol. Hence, option 'B' is correct.

• The reaction will get stable only when it will release a large amount of energy and gets stable.
• Exothermic reactions release energy after the formation of products and lead to stabilization.
• The higher the energy released, the more stable the product formed.
• As we can see the largest negative energy (negative sign represents the release of energy) with the combustion reaction of Carbon. Hence, it will become the most stable, and Option 'B' is correct.

Hence, The Reaction giving the most stable product is C(s) + O2(g) ----> CO2(g) ∆H = -393.5kJ/mol.
