السلام عليكم
بديت في الكيمياء من دحين وخلصت الشابتر 14 بس في ثلاثه اسئله ضعت فيها ،
تكيت عليها لين اطلع الحل بس ما عرفت
ف يآ ليت الي مذاكر دا الشابتر وفاهم فيه
يقرأ وينززل تحت بالرد ويكتب الجواب
(1) The reaction A+2B = c was allowed to come to equilibrium. The initial amounts of reactants placed into a 5.0L vessel were 1 mol and A 1.8 mol B . After the reaction reached equilibrium, 1 mol of B was
found . Calculate kc for this reaction.
(2) Which equilibrium is correctly matched to the shift in reaction when the pressure is decreased by increasing the volume?
a) C6H12= C6H6 + 3H2
b) CL2 + 2NO2 = 2CINO2
c) PBR3+ BR2 = PBR5
d) H2o + ch4 = CO + 3H2
(3) kc = 0,534 at 700c for the reaction:
H2 + co2 = h2o + co
Calculate the number of moles of H2 present at equilibrium if a mixture of 0.300moles of H2O and 0.300 moles of co is heated to 700c in a 10.0 L contaier .
