- Heating a metal carbonate leads to decomposition. BaCO3(s) BaO(s) + CO2(g) Predict the effect on the equilibrium of each change listed below. Answer by choosing (i) no change, (ii) shifts left or (iii) shifts right. (a) add BaCO3 (b) add CO2 (c) add BaO (d) raise the temperature (e) increase the volume of the flask containing the reactionarrow_forwardPhosphorus pentachloride decomposes to phosphorus trichloride and chlorine gas at elevated temperatures by the following reaction: PCl5(g) ⇌ PCl3(g) + Cl2(g). If Kc = 5.7 at 120°C, what is the value of Kp at the same temperature?arrow_forwardReaction of nitrogen and hydrogen in the presence of a catalyst produces ammonia: N2 + 3H2 2NH3 , rHo = -92 kJ mol-1 . What would increase equilibrium concentration of the product in the mixture? A) Increase pressure, keep temperature constant B)Increase temperature, keep pressure constant C) Decrease pressure, keep temperature constant D) Information is insufficient for answerarrow_forward
- The decomposition of dinitrogen tetroxide gas forms nitrogen dioxide gas. What is the value of Kc at 100C if reaction mixture at equilibrium contains [N2O4]= 0.45M and [NO2]= 0.31M ?arrow_forwardThe calculated value of KP for the equilibrium: 2 NO(g) + Cl2(g) 2 NOCl(g) is 4.46e-01 at 417 oC. For each of the mixtures described in the multiple choices figure out whether the mixture is reasonably close to being at equilibrium at 417 oC. "Reasonably close" means that Q is within a factor of 2 of KP. If the mixture is not close to equilibrium figure out which direction the reaction will shift (toward product or toward reactants) to achieve equilibrium. Choose the correct statement from the choices.arrow_forwardFor the reaction: CrCl3(TAP)(s) qe CrCl3(g) + TAP(g), Kc = 4.23*1014 (513 K), TAP = 1,3,5-triaminopentane What is the value of Kp at 513 K?arrow_forward
- For a reversible reaction, Kp = 23 and Q = 11. Which statement does not accurately describe this reaction at this moment? Question options: The reverse reaction rate is faster than the forward reaction rate. The reaction is not at equilibrium. The concentrations of the products will be higher at equilibrium than they are now. The forward reaction rate is faster than the reverse reaction rate.arrow_forwardPhosgene (COCl2) is used in the manufacture of foam rubber and bulletproof glass. It is formed from carbon monoxide and chlorine in the following reaction:$$Cl2(g)+CO(g)COCl2(g) See Periodic Table The value of Kc for the reaction is 10.9 at 525.4 °C. What is the value of Kp at 525.4 °C?arrow_forwardConsider the reaction NiO(s) + CO(g) ⇌ Ni(s) + CO2(g) Kp = 4.0 × 103 at 1500 K If a mixture of solid nickel(II) oxide and 4.0 atm carbon monoxide comes to equilibrium at 1500 K, what is the equilibrium pressure of CO2? Report your answer to two significant figures. Do not include units in your answer.arrow_forward
- The following reaction can be used to make H2 for the synthesis of ammonia from the greenhouse gases carbon dioxide and methane: CH4 (g) + CO2 (g) ⇌ 2 CO (g) + 2 H2 (g) At 1200. K, Kp = 3.548 × 106. What is the partial pressure of CH4 at equilibrium when 10.00 atm of CH4 reacts with 15.00 atm of CO2 at 1200. K? Use small x approximationarrow_forwardFor the gaseous reaction, 2 H2 + 2 NO <=> 2 H2O + N2, Kp at 120oC = 2.42. At a given moment, it is found that the partial pressures of H2, NO, H2O and N2 are 1.1, 1.3, 0.78 and 2.2 atm, respectively. Which of the following statements describes the situation? Group of answer choices Qp = 1.2 so the reaction goes to the right Qp = 0.65 so the reaction goes to the left The reaction is at equilibrium Qp = 0.65 so the reaction goes to the right Qp = 1.2 so the reaction goes to the leftarrow_forwardPhosgene (COCl2) is used in the manufacture of foam rubber and bulletproof glass.
