Of course, this is an equilibrium reaction: $2HI(g) rightleftharpoons I_2(g) + H_2(g)$, in which there is equality of forward and reverse rates. I could equally write, $I_2(g) + H_2(g)...

1 Answers 1 viewsThe reaction rate is a direct function of the reactants concentrations, aA+ bB → cC $"Rate" = k[A]^x [B]^y$ Where $a, b, c$: are the stoichiometric coefficients $x, y$:...
1 Answers 1 viewsEven without doing any calculation, you should be able to look at the values given for the equilibrium concentrations of the three chemical species that take part in the reaction...
1 Answers 1 viewsBecause ferrous oxide and iron are solids, they cannot express a concentration, and thus they do not appear in the equilibrium expression. The equilibrium depends solely on the concentrations, or...
1 Answers 1 viewsUse the definition of $K_(eq)$. $K_(eq) = (["products"]^(d,e,f, . . . ))/(["reactants"]^(a,b,c,. . . ))$ $= (["NH"_3]_(eq)^2)/(["H"_2]_(eq)^3["N"_2]_(eq))$ Just make sure you remember to use stoichiometric coefficients correctly. $3H_2$...
1 Answers 1 viewsWell, I would never recommend this "trial-and-error" method... I don't see why you should ever "have" to do it... just use the quadratic formula on the resulting quadratic equation. I...
1 Answers 1 viewsThe equilibrium concentrations for all the species involved in the reaction are as follows: $[HI] = "1.87 M"$ $[H_2] = "0.107 M"$ $[I_2] = "0.00660 M"$ So, start with the...
1 Answers 1 viewsSo, you know that you're dealing with an equilibrium reaction that has its equal to 96.2 at a certain temperature. The fact that $K_c$ is larger than one tells...
