A
q = 2.303 nRT log V₂/V₁
B
q = -2.303 nRT log V₂/V₁
C
q = -nRT log V₂/V₁
D
q = -Pₑₓₚ nRT log V₂/V₁
Correct Answer
Option A
Detailed Explanation
In an isothermal reversible expansion, the heat exchanged q is given by q = 2.303 nRT log V₂/V₁, where V₂ and V₁ are the final and initial volumes respectively.
