According to the Bronsted-Lowry definition,
1 answer:
Answer:
The correct answer is 'a base is a proton acceptor .'
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses or donates protons and forms conjugate base.
Acid → + Conjugate base
- A base is defined as a substance which accepts protons and forms conjugate acid.
Base + → Conjugate acid
According to the question the correct answer is 'a base is a proton acceptor.

Answer:
The value of entropy change for the process
Explanation:
Mass of the ideal gas = 0.0027 kilo mol
Initial volume = 4 L
Final volume = 6 L
Gas constant for this ideal gas ( R ) =
Where = Universal gas constant = 8.314
⇒ Gas constant R = 8.314 × 0.0027 = 0.0224
Entropy change at constant temperature is given by,
Put all the values in above formula we get,
This is the value of entropy change for the process.
