(c) 4. Consider the following balanced chemical equation: 2 NO2 (g) N204 (g) Which of graphs below could correctly illustrate the outcome of this reaction at 273 K? (a) Concentration (mol/L) Concentration (mol/L) Time (s) Time (s) NO₂ N204 NO₂ N2O4 (d) (b) Concentration (mol/L) Concentration (mol/L) K 1000 at 273K Time (s) Time (s) N2O4 NO2 N₂04 NO₂

Nitrogen dioxide and water react to form nitric acid and nitrogen monoxide, like this: 3 NO₂(g) + H₂O(1)→2 HNO3(aq) + NO(g) At a certain temperature, a chemist finds that a 3.4 L reaction vessel containing a mixture of nitrogen dioxide, water, nitric acid, and nitrogen monoxide at equilibrium has the following composition: compound NO₂ H₂O HNO3 NO amount 5.9 g 142.0 g 15.1 g 12.0 g Calculate the value of the equilibrium constant K for this reaction. Round your answer to 2 significant digits. с K = D 0 C x10 X Ś

For the following reaction, N204(g) → 2NO2(g), the value of Ke is 1.2x10-5 at a certain temperature. If the reaction mixture is found to contain 0.0020 M NO2 and 0.0075 M N204, what is the value of Q and what does this mean? Periodic Table and Datasheet Q K and the reaction will proceed towards the reactants. Q > K and the reaction will proceed towards the products.

ONLY LOOKING FOR THE ANSWER TO PART B. I already got part one!

thx in advance :)

Consider the quilibrium reaction between X and Y, as shown below: X=Y AG The reaction is started with 10 mmol of X; no Y is initially present. After 48 hours, analysis reveals the presence of 10 mmol of X and 0 mmol of Y. Which is the most likely explanation? = −1 - 45 kJ mol X and Y have reached equilibrium concentrations. An enzyme has shifted the equilibrium toward X. Formation of Y is kinetically slow; equilibrium has not been reached by 48 hours. Formation of Y is thermodynamically unfavorable. Two of the above explanations are reasonable.

2) For the reaction, PCI:(g) = PCl:(g) + Ch(g) at 327°C, the equilibrium constant, Ke is 0.234. Suppose that 2.082 g PCIIS is placed in an evacuated 200 mL bulb, which is then heated to 327°C. (R = 0.082 L atm mol'K', PCIS = 208.2 g/mol) (a) What would be the pressure of PCIs if it did not dissociate? (b) What is the partial pressure of PCIS at equilibrium? (c) What is the total pressure in the bulb at equilibrium? (d) What is the fraction of PCIS at cquilibrium?

Explain your reasoning, please. Thank you.

Explain what is going on in these photos and explain the graphs

Write the equilibrium expression for the following: I2(s) + 3XeF2(s) ↔↔ 2IF3(s) + 3Xe(g)
