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.
Explain your reasoning, please. Thank you.

The Scenario Professor Ndekele asks you to test a new low temperature catalyst for the decomposition of ammonia, NH3. With previously existing catalysts decomposing ammonia requires a temperature of 450 ºC, but this new catalyst is said to be effective at a temperature of 100 ºC! You plan to heat ammonia gas with the catalyst in a flask connected to a manometer and track the reaction by the change in pressure, which should increase as the temperature increases and as the reaction progresses and the number of moles of gas increases via the balanced chemical equation: 2 NH3 (g) → N2 (g) + 3 H2 (g) You make the following observations. Observations Vflask = 1.00 L Patm = 630.5 mmHg TRoom = 23.2 ºC Before heating h = 0.00 As you heat the flask, the mercury falls on the flask side of the manometer and rises on the open end. At 100.0 ºC, the height difference in the flask is 65.5 cm. Analysis **convert all T-values to K for gas law calculations! Use the ideal gas equation to…
