JEE Advanced Chemistry Question (2024) — Solution

Question

Consider the following volume-temperature ( V - T ) diagram for the expansion of 5 moles of an ideal monoatomic gas. Considering only P-V work is involved, the total change in enthalpy (in Joule) for the transformation of state in the sequence X Y Z is ________. [Use the given data: Molar heat capacity of the gas for the given temperature range, C _ V , m =12 ~J ~K ^ -1 mol ^ -1 and gas constant, . R =8.3 ~J ~K ^ -1 ~mol ^ -1 ]

Options

  1. A. A
  2. B. B
  3. C. C
  4. D. D

Answer

A. A

Step-by-step solution

For ideal gas H = nC _ P T C _ P = C _ V + R =12+8.3=20.3 ~J / K -mole H=5 20.3 (415-335) H=8120 Joule
