JEE Advanced 2025 Chemistry question
An electrochemical cell is fueled by the combustion of butane at 1 bar and 298 K. Its cell potential is volts, where F is the Faraday constant. The value of X is . Use: Standard Gibbs energies of formation at 298 K are: kJ mol⁻¹; kJ mol⁻¹; kJ mol⁻¹
Answer: 105.5
Solution
: kJ mol⁻¹. Carbon goes from −2.5 (average) to +4, so n
