Question 64
GGNAT2 marksNeeds review
The following reaction occurs at 1 bar and 823 K.
Grossular + Quartz = Anorthite + 2 Wollastonite
Mineral | Entropy (S¹, 823) kJ K⁻¹ | Volume (V¹, 823) J bar⁻¹ |
|---|---|---|
Grossular | 0.255 | 12.535 |
Quartz | 0.042 | 2.269 |
Anorthite | 0.200 | 10.079 |
Wollastonite | 0.082 | 3.993 |
Using the above molar thermodynamic data, the calculated slope of the above reaction is _______ bar K⁻¹. [round off to 2 decimal places]
