Solve 3 Chemical Equilibrium Questions & Calculate Kc

AI Thread Summary
The discussion revolves around solving three chemical equilibrium questions and calculating equilibrium constants (Kc). The first question highlights that two systems cannot be in equilibrium at a given temperature due to a single Kc value, emphasizing the importance of concentration units in Kc calculations. The second question compares two temperatures, T1 and T2, to determine where the amount of product B will be higher, with a focus on the relationship between temperature and equilibrium concentrations. The third question involves calculating Kc for a reaction involving CO2 and H2, given specific conditions in a rigid container. The thread seeks assistance in understanding these concepts and calculations.

Hi, I have 3 questions i can't seem to solve anyways thanks in advance.

1) If the equilbrium constant at a cetain temperature is 24 for the reaction, 2NO(g) <-> N2(g) + 02(g). Both of the systems listed below cannon be in equilbrium because at this temperature because there is only one value of Kc.

[NO] = System 1 - System 2
1.06 1.56
[N2]
[O2]

Since the equilbrium constant does not have units it doesn't matter which unit we use for concentration when calculating Kc.

2a) At T1, K=0.013
At T2, K = 083

If 1.00 mole of A is placed in a 1.00L reaction vessel, at which temperature will the amount of B at equilbfrium be higher? Explain your answer.

2b) If delta H < 0, which temperature is higher? T1 or T2? Explain your answer.

3) Use the information below to calculate Kc for the follwing reactiosn at 600 decrees celcius

C02(g) + H2(g) <-> CO(g) + H2O(g)

A gas mixture that consits of equal amounts of Co and H20 was injected into a 1.97 rigid walled container at 600 degreees ceclius until the pressure reached 7.25 atm. When the reaction reaced equilbirum, 0.024 mole Of CO were present.

Thx much.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
