Calculate the enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions. K+S → KSAH = +32.5 kJ KS + K + KS AH = +38.2 kJ​

Answer :

OKPALAWALTER8GO

The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as

dn=70.7kg

What is the enthalpy change for the reaction?

Generally, the equation for the  Chemical reaction is mathematically given as

2k+s----->K2S

Therefore

KS+K----->K2S

Therefore

dn=dn1+dn2

dn=32.5+38.2

dn=70.7kg

In conclusion,  the enthalpy change is

dn=70.7kg
