a) Find q, w , ∆E when a system gains 10.0 kJ of heat from the
surroundings and does 14.0 KJ of work on the surroundings.
b) If the standard enthalpy of reaction , ∆Ho , is
-137.0 kJ for the chemical reaction
C2H4(g) + H2(g) →
C2H6(g) How much heat is liberated
when 400.0 g of C2H6 is produced ?
c) Given the following thermochemical reactions:
CH4 (g) + 1/2 O2(g) → CH3OH
(l) ∆Ho = -163.9 kJ
CO2...
