When conducting chemical reactions in the lab or in industrial processes, it can be important to know whether a reaction has reached equilibrium. By measuring the reaction quotient, Q, of a chemical reaction and comparing it to the equilibrium constant, K, we can identify whether a reaction is at equilibrium. For the reaction aA+bB⇌cC+dD the reaction quotient, Q, is given by the expression Q=[C]c[D]d[A]a[B]b under any conditions. The value of Q is equal to K only at equilibrium.

Part B

The following reaction was carried out in a 2.50 L reaction vessel at 1100 K:

C(s)+H2O(g)⇌CO(g)+H2(g)

If during the course of the reaction, the vessel is found to contain 10.0 mol of C, 14.7 mol of H2O, 3.60 mol of CO, and 7.60 mol of H2, what is the reaction quotient Q?

Enter the reaction quotient numerically

Part C

The reaction

2CH4(g)⇌C2H2(g)+3H2(g)

has an equilibrium constant of K = 0.154.

If 6.30 mol of CH4, 4.50 mol of C2H2, and 11.35 mol of H2 are added to a reaction vessel with a volume of 6.00 L , what net reaction will occur?

The reaction

has an equilibrium constant of  = 0.154.

If 6.30  of , 4.50  of , and 11.35  of  are added to a reaction vessel with a volume of 6.00  , what net reaction will occur?

-The reaction will proceed to the left to establish equilibrium.
- The reaction will proceed to the right to establish equilibrium.
-No further reaction will occur because the reaction is at equilibrium.

In the bromination and debromination lab what exactly is happening? Is there any Chemical reactions? This is what we did in the lab. Added 100 mL of acetic acid into a test tube, and placed it in a warm water bath. We then weighed 400 mg of NaBr, 90 mg of Sodium Bromate (NaBrO3) and 100 mg of stilbene. We then added all those compounds to the test tube containing the acetic acid and once the color of the solution...

Heat effects of chemical or physical processes can be measured in a calorimeter.
Can someone please paraphrase this to me.... if possible. Heat effects of chemical or physical processes can be measured in a calorimeter. Instruments of widely varying designs are employed to accommodate the large range of experimental conditions encountered. For instance, the heat effects to be measured may range from milliJoules to milliliter, quantities involved from fractions of milliliters to hundreds of milliliters and from milligrams to grams, operating temperatures from below liquid helium temperature (4.2 K) to 2000o C, and...

When conducting a research on issues on the Effective Treatments for Chemical Dependency, The research question is; “How effective are the various methods of treatments for chemical dependency?” And the testable hypothesis is; “when the body is dependent on chemicals to be able to operate and/or function, it appears like the body finds it difficult to transition into full recovery mode despite all the treatment methods for chemical dependency.” How many participants would you like to use and why?
