[填空题]
The feasibility of a reaction proceed:gj y992fnan g;shy )zing spontaneousld9iet2e9etxhw t;8 r8y can be predicted using the fte2e8 8ti de htx9;9rwollowing equation:
ΔG=−TΔS+ΔH.
Where ΔG is the change in Gibb’s free energy, ΔS is the change in entropy, and ΔH is the change in enthalpy.
1.When ΔG<0, a reaction can be described as spontaneous. Use the graph above to deduce the lowest temperature at Read graph at which the reaction becomes spontaneous.
Read graph at ΔG=0, K.
2.Calculate the gradient of the line and state its units.
3.Use your answer to part (b) to deduce the value and correct units for ΔS.
ΔS= kJ molK 4.Use the graph to determine the value for ΔG when the temperature is raised to 675K.
5.Calculate a value for y-intercept and state the correct units.
Substitution of (x,y) values and slope into equation with correct evaluation= .(c=)
