Answer 1

Answer #1

H₂O (s) To H₂O (l)

T = -10^oC

Convert temperature to kelvin

Temperature in K = (273.15+(-10)) = 263.15 K

Δ H = 6.01 kJ/mol

Convert 6.01 KJ/ mol to J/mol:

1 kJ = 10³ J

6.01 x 10³ J/Mol = 6010 J/K

Step 1: Calculate AS or A System AS-- shfus J/K ASE-9930J/K AS = 22.00 J/K 273.15 Step 2: Calculate A S surrounding A Ssurrou

Since Δ S_{total = -ve hence the process is
non-spontaneous.}
