P4O10(s) = -3110 kJ/mol H2O(l) = -286 kJ/mol H3PO4(s) = -1279 kJ/mol Calculate the change in enthalpy for the following process:
mash [69]

Answer:

-290KJ/mol

Explanation:

ΔHrxn = ΔHproduct - ΔHreactant

ΔHrxn= 4ΔHH3PO4 - {6ΔHH2O + ΔHP4O10}

ΔHrxn = 4(-1279) - [6(-286) - 3110]

= -5116 -(-1716-3110)

= -5116-(-4826)

= -5116 + 4826 = -290KJ/mol

What is the change in enthalpy when 4.00 mol of sulfur trioxide decomposes to sulfur dioxide and oxygen gas? 250 2(g) + O2(g) ®
lidiya [134]

Answer: A. -396 kJ

Explanation:

The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.

2SO_2(g)+O_2 (g)\rightarrow 2SO_3(g)  \Delta H^0=198kJ

Reversing the reaction, changes the sign of \Delta H

2SO_3(g)\rightarrow 2SO_2(g)+O_2 (g)  \Delta H^0=-198kJ

On multiplying the reaction by 2, enthalpy gets multiplied by 2:

4SO_3(g)\rightarrow 4SO_2(g)+2O_2 (g)   \Delta H=2\times -198kJ=-396kJ

Thus the enthalpy change for the reaction 4SO_3(g)\rightarrow 4SO_2(g)+2O_2 (g)  is -396 kJ.
