Given the information in the photo how would this question be solved?

Based on the equation and the information in the table, what is the enthalpy of the reaction?

8) a mixture of he, ne and ar has a pressure of 7.85 atm. if the ne has a mole fraction of 0.47 and 8) ar has a mole fraction of 0.23, what is the pressure of he? a) 4.2 atm b) 3.7 atm c) 5.5 atm d) 2.4 atm e) 1.8 atm

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
