Question
Consider the following reaction.CH3OH(g) CO(g) + 2 H2(g) H = +90.7 kJ
(a) Is the reaction exothermic or endothermic?
endothermic
exothermic
(b) Calculate the amount of heat transferred when 50.0 g of CH3OH(g) are decomposed by this reaction at constant pressure.
H =
kJ
(c) If the enthalpy change is 13.0 kJ, how many grams of hydrogen gas are produced?
g
(d) How many kilojoules of heat are released when 13.0 g of CO(g) reacts completely with H2(g) to form CH3OH(g) at constant pressure?
H =
kJ
(e) Calculate E when 340.0 g of CH3OH(g) completely reacts at a constant temperature of 300 K and constant pressure of 0.95 atm. R = 8.314 J/mol*K and R = 0.08206 atm*L/mol*K
