Which of the following conditions is always true at equilibrium. So there are two boxes where I have to sort the choices in. Box number 1 is called True at equilibrium. Box number 2 is called Not necessarily true at equilibrium. Choices are. a)delta G=0. b)delta G^*=0. c)delta G = delta G^* d)Q=0 . e)delta G^*=1. f)Q=1. g)K=1For each: Always true /sometimes true/never true. 1) the joule is the SI unit of force 2)the standard heat of formation for a substance is determined at 100 degrees C 3)all free elements in their standard states have a heat of formation of zero. Chemistry (Check) Classify each of these statements as always true, sometimes true or never trueWhich of the following describes a Nash equilibrium? a. A firm chooses its dominant strategy, if one exists. Which one of the following conditions is required for the success of a tit-for-tat strategy? a. Demand and cost conditions must change frequently and unpredictably. b. The number of oligopolists in the industry must be relativelyLe Chatelier's principle addresses how an equilibrium shifts when the conditions of an equilibrium are changed. The direction of shift can be predicted for changes in concentrations, temperature, or pressure. Catalysts do not affect the position of an equilibrium; they help reactions achieve equilibrium faster.The following is true about the equilibrium constant. It relates the ratio of the concentrations of products to reactants once the reaction has reached chemical equilibrium. The equilibrium constant is the ratio of product of the equilibrium

Which of the following conditions is always true at

For a reaction system which is at equilibrium, which of the following must always be true? A) q = 0 B) ΔH = 0 C) ΔS = 0 D) ΔU = 0 E) ΔG = 0Consider the following reaction: I2(g) + Cl2(g) 2ICl(g) o Kp = 81.9 at 25 C. Calculate ∆Grxn for the reaction at 25 C under each of the following conditions: a Standard conditions. b At equilibrium. c PICl = 2.55 atm; PI2 = ChemWhich of the following conditions is always true at equilibrium?

Now suppose we were to superheat 1 mol of liquid water to 110°C. The value of ΔG for the vaporization of 1 mol of water at 110°C, assuming that ΔH and ΔS do not change significantly with temperature, becomes

Which of the following is true of the output level produced by a firm in long-run equilibrium in a monopolistically competitive industry? A) It produces at minimum average cost. B) It does not produce at minimum average cost, and average cost is increasing. C) It does not produce at minimum average cost, and average cost is decreasing.Question: Which Of The Following Conditions Is Always True At Equilibrium? This problem has been solved! See the answer.

Questions

Which of the following conditions is always true at equilibrium? deltaG=0, Q=1, Okay=1, deltaG=deltaG(same old), deltaG(usual)=0, Q=0, deltaG(same old)=1

I'm so confused, please assist!

Here are the formulation that you need.

ΔG=-RT*lnK

ΔG=ΔGo'+RTlnQ

At equilibrium, Q=Okay, If K=1 then Q=1.

ln(1)=0, so ΔG=ΔGo'+RTln(1) becomes ΔG=ΔGo'

Now if Q=K, then K=1

ln(1)=0, so ΔG=-RT*ln(1)=0. So, ΔG=0.

The last 3, deltaG(usual)=0, Q=0, deltaG(same old)=1, are mistaken, I consider.

I would cross with dG = 0

It was once a typo. When I did the paintings, I confirmed that it does equivalent 0. just did not disregard it.

My unique post should say the closing two, Q=0, deltaG(same old)=1, are wrong.

Oh, my original submit used to be correct. the last 3 are false. deltaG(same old)=ΔGo'=0 is false. Its either certain or destructive, but it does not rely on K or Q.

The solution is dg=Zero most effective. The different conditions might occur at equilibrium however aren't always the case.

Court and Bob, you're right kind. The manner that I went about solving the drawback, I imagine, is simplest true for same old conditions; the downside did not state usual conditions.
