Question

Calculate the enthalpy change when 1 kg ice melts. ΔHfusion = 6.009 kJ/mol
a. 111 kJ/mol
b. 223 kJ/mol
c. 334 kJ/mol
d. 445 kJ/mol

science chemistry

Answer 1

Answer #1

The conversion of solid to liquid is called melt.

The enthalpy or heat required for this process is called heat of fusion ( ΔH_fusion) .

The enthalpy change when 1kg ice melts is 334 KJ.

so option C is the correct answer.

The detail explanation is shown below.

Ah susion = 6.009 kJ/mole. the enthalpy required for conversion I mole of solid in to liquid is 6.009 KI. Imola of ice (H2O)
