Question
THERMODYNAMICS: Calculate the value of AH (in kJ) for the reaction, 2AR3 (g) + Q (s) → A2R4 (g) + QR2 (s) given the
following hypothetical thermochemical equations:
AH = -86.4 kJ
AH = -159.8 kJ
2AR3 (g) + 2AX (g) → A2R4 (g) + 2XAR (g)
AX (g) + ½R2 (g) → XAR (g)
Q (s) + R2 (g) → QR2 (s)
(Round off final answer to ONE decimal place)
AH = -516.3 kJ
