Predict whether S for each reaction would be greater than zero, less than zero, or too close to zero to decide.

Clear All
I2(g) + Cl2(g)2ICl(g)
PCl5(g)PCl3(g) + Cl2(g)
2HBr(g) + Cl2(g)2HCl(g) + Br2(g)
2H2S(g) + 3O2(g)2H2O(g) + 2SO2(g)
2H2O(l)2H2(g) + O2(g)

S > 0
S < 0
too close to decide

Answer 1

NOTE: According to the question we have to predict only that whether is the enropy will be greater than zero , less than zero ,too close to zero.

so in the solution here is only predicted the S. this is not the value for the change in entropy for the reaction .

for your solution kindly see in the Picture

In this question we have to predict only that whether is .. will be +ve.. will be -ve are equal to zero.

So we have to predict the vlue of as follows:
