When it comes to equilibrium reactions, it useful to do ICE analysis. ICE stands for Initial-Change-Equilibrium. You subtract the initial and change to determine the equilibrium amounts which is the basis for Kc. Kc is the equilibrium constant of concentration which is just the ratio of products to reactant.
Let's do the ICE analysis
2 NH₃ ⇄ N₂ + 3 H₂
I 0 1.3 1.65
C +2x -x -3x
-------------------------------------
E 0.1 ? ?
The variable x is the amount of moles of the substances that reacted. You apply the stoichiometric coefficients by multiplying it by x. Now, we can solve x by:
Equilibrium NH₃ = 0.1 = 0 + 2x
x = 0.05 mol
Therefore,
Equilibrium H₂ = 1.65 - 3(0.05) = 1.5 molEquilibrium N₂ = 1..3 - 0.05 = 1.25 mol
For the second part, I am confused with the given reaction because the stoichiometric coefficients do not balance which violates the law of conservation of mass. But you should remember that the Kc values might differ because of the stoichiometric coefficient. For a reaction: aA + bB ⇄ cC, the Kc for this is
Hence, Kc could vary depending on the stoichiometric coefficients of the reaction.
What are the options because i think it is HCl and it has H+ as a common ion
Laminin. It is called Laminin. Funny thing is, is that it is shaped like the cross on which Jesus died... What a <span>coincidence! :D</span>
The best answer for this question is <span>d. A person should seek treatment the first moment he or she suspects having an STI.</span><span>
The moment a person suspects that he/she has an STI, that person must immediately have him/her self checked by a doctor. The earlier an STI can be diagnosed, the earlier it can be treated. A person does not have to wait for a symptom to appear before treating the infection.</span>
Answer:
the higher the kinetic energy
Explanation:
because their will be easy movement of particles.
