Consider the following chemical equilibrium:

jok3333 [9.3K]

Answer:

Kc = [CH₄] / [H₂]²

Kp = [CH₄] / [H₂]² * (0.082*T)^-1

Explanation:

Equilibrium constant, Kc, is defined as the ratio of the concentrations of the products over the reactants. Also, each concentration of product of reactant is powered to its coefficient.

Pure solids and liquids are not taken into account in an equilibrium

Thus, for the reaction:

C(s)+ 2H₂(g) ⇌ CH₄(g)

Equilibrium constant is:

Now, using the formula:

Kp = Kc* (RT)^Δn

Where R is gas constant (0.082atmL/molK), T is the temperature of the reaction and Δn is difference in coefficients of gas products - coefficients of gas reactants (1 - 2= -1)

1. An atom that has an outer shell that is NOT full is (more likely OR less likely) to be reactive than an atom that has a full

Serga [27]

Yes because they atom with a stable octet electrons is less reactive it does not need any more electrons while an atom that has an partially filled electrons need more electrons to complete octet structure

Select the correct order of the GC components

Carrier Gas, Flow Controller, Column, Detector, Recorder

First we have a cylinder containing the carrier gas. From there, the carrier gas goes to the flow controller, which determines how much carrier gas we are entering into the column (it doesn’t let more gas pass through). Then, the carrier gas enters the column, which is the most important part of the device. The sample enters the column from another place: the injector. Then, the sample and the carrier gas go together across the column. The interactions between the sample and the column will determine how fast each sample component goes through the column, and so: which component gets out earlier. So, at the end, you will have isolated each substance. Then, each one passes (alone) through the detector, which measures something about the sample – this information will let you know which substance it is. Finally, the recorder provides you with the information the detector has found. Nowadays, the recorder is a computer. In the “stone age” they just used a rudimentary printer.
