What can be said about the reaction 2NH3 g N2 g 3H2 g H 92.4 kJ mol?
The Reaction is Endothermic
What can be said about a reaction with h=-890 kj/mol and s = -0.24 kj/mol?
It can be said to be exothermic since H is negative. Also below a temp of 3708ºC, the reaction will be spontaneous because ∆G will be negative. This is from ∆G = ∆H - T∆S.
If a temperature increase from 22.0 to 34.0 triples the rate constant for a reaction what is the value of the activation barrier for the reaction?
69.0kJ/mol
How many moles of iron can be produced from the reaction of 10 mol Fe2O3 and 25 mol of CO?
17
If 6 moles of a compound produce 84 J of energy what is the H reaction in J mol?
-14 J/Mol

Use the reaction I2(s) I2(g), H = 62.4 kJ/mol, S = 0.145 kJ/(molK), for this question What can be said about the reaction at 500 K?
It is spontaneous.
What can be said about a reaction with H equals -890 kJ mol and S equals -0.24 kJ molK?
It is spontaneous at 2000 K.
What can be said about 1 mol Ag and mol Au?
1 mol of Ag and 1 mol of Au can be said to contain the same amount of atoms of each element.

-14 J/Mol
What is the maximum mass of iron metal if 50.0 grams of ironIII oxide is mixed with 50.0 grams of aluminum?
Fe2O3 + 2Al --> 2Fe + Al2O3Before:50.0g + 50.0g > 0.0g + (not important)159.69(g/mol) + 26.98(g/mol)In mol (before reaction):+0.3131 mol + 1.853 mol (excess)Reaction (used reactant > formed Fe):-0.3131 mol - 0.6262 mol > + 0.6262 mol FeRemaining (= before - used):0.0 mol Fe2O3 + 1.227 mol Al > 0.6262 mol Fe, this should be multiplied by the molar mass of Fe to get mass in grams: 0.6262 (molFe) * 55.85 (g/molFe) = 34.97 = 35.0 g Fe
How many moles of CO are produced when 1.4 moles of C reacts?
If you have 1.4 mol of carbon before the reaction you have 1,4 mol of carbon after the reaction. If you make carbon monoxide, CO, then you need 1.4 mol of CO after the reactiion. If you make carbon dioxide, CO2, you need 1.4 mol of C2O, because you have one carbon in each molecule.
Suppose you react 6.33 mol calcium with 4.00 mol oxygen gas What the number of moles of oxygen left over after the reaction is complete?
Suppose we react 6.00 moles calcium with 4.00 mol oxygen gas. Determine the number of moles of oxygen left over after the reaction is complete.
