- Answer this problem.arrow_forwardConsider the following reversible reaction at equilibrium: C6H12O6(aq) + 6 O2(g) 6 CO2(g) + 6 H2O(l). Given that this reaction is exothermic, if heat is added to the equilibrium system, how is the stress relieved?arrow_forward9.Suppose 1.000 mole of CO and 3.000 mol of Hydrogen are put in a 10.000 L vessel at 1200 K. Determine the equilibrium composition of the reaction mixture if K. = 3.92 for the reaction. CO (g) + 3H₂(g) → CH4(g) + H₂O(g)arrow_forward
- Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 500. mL flask with 3.4 atm of ammonia gas, and when the mixture has come to equilibrium measures the amount of nitrogen gas to be 1.4 atm. Calculate the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits. K, = 0 Ox10arrow_forwardAt - 17.6 °C the pressure equilibrium constant K₁ = 5.1 × 105 for a certain reaction. Here are some facts about the reaction: • The net change in moles of gases is -1. • If the reaction is run at constant pressure, 129. kJ/mol of heat are absorbed. • If the reaction is run at constant pressure, the volume increases by 14.%. Yes. ☐ x10 Using these facts, can you calculate K, at -41. °C? No. Х If you said yes, then enter your answer at right. Round it to 2 significant digits. at If you said no, can you at least decide whether Kp -41. °C will be bigger or smaller than K, at − 17.6 °C? P Yes, and K, will be bigger. Yes, and K,, will be Р smaller. ○ No.arrow_forwardPlease provide proper explanation.arrow_forward
- Some Chem 16.1 students were tasked to perform the ideal gas experiment with some modifications. Instead of magnesium ribbon, the students were to use 0.029 g of aluminum foil. They prepared the eudiometer by adding 6M HCI and filling it with water to the brim. Once the setup was complete, they performed the experiment. Note that the aluminum was completely consumed in the reaction. From the experiment, it was found that the external pressure was 1.05 atm at 30.0 °C, and the volume of the air inside the eudiometer was 33.5 mL. The water level inside the eudiometer is 4.15 cm below the surface of the water level outside. Given these measurements and the following constants, answer the proceeding questions. At 30.0°C, Pvapor = 31.8 mmHg • R = 0.08206 L-atm/mol-K = 62.36 L-torr/mol-K • MWAI = 26.98 g/mol A. Find the value of the pressure of dry air (PDA) in torr. B.
