mast y.com/myct/itemView?assignmentProblemiD 98002096 Enthalpy of Reaction: State and Stoichiometry (?) 11of11 The ex than the elements in their standard states Substance | ? (kJ/mol) C(g) - Part D 718.4 -6799 -74.8 217 94 -268.61 suppose tha 0490 m ol o methane, H?R, s reacted with 0 640 mol of fluonne, F2 (g forming CF, (g) ad HF (g) as sole pro acts. CH(8) H(g) HF(8) Assuming that the reaction occurs at constant pressure, how much heat is released? Express your answer to three significant figures and include the appropriate units. View Available Hint(s) heat Value Units Incorrect; Try Again; 4 attempts remaining

Explanation / Answer

Only 1 mole of CH4 are participated in the reaction hence

Heat released= mole of methane *heat eve of methane

= .490*-74.8

=36.652 kj heat are released
