A plot of ΔG (in units of kJ/mol) vs. T (K) yields a straight line with the equation: y = -10.935x + 114.5. What is the value of ΔH (kJ/mol) for the reaction, based on this data?
Express your response to two digits after the decimal.
Homework Answers
Solution:
When free energy change (ΔG) is plotted against temperature (T), then intercept (c) of the straight line is equal to the enthalpy change (ΔH).
y = -10.935 x + 114.5
Comparing the above equation with straight line equation,
y = mx + c
Since,
c = 114.5
Hence,
ΔH = 114.50 kJ/mol
