Answer to Question #251484 in General Chemistry for Mallorie

Question

A certain reaction has TriangleH(degree symbol) = -73.80 kJ and TriangleS(degree symbol) = 0.00 J/K

A) Is this reaction is exothermic

B) Does this reaction lead to a decrease, an increase, or no change in the degree of disorder in the system? _______

C) Calculate triangleG(degree symbol) for this reaction at 298 K. If this value is less than 1 kJ/mol than enter O in the answer box.

TriangleG(degree symbol) = _____ kJ

D) Under the standard conditions at 298 K, this reaction is spontaneous.

Answer 1

1)since Ho is greater than 0, the reacion is endothermic

b)it increases the degree of randomess

c)Go=Ho-TSo

=7.488 kJ/mol

d)the reaction is non spontaneous since Go is positive
