- Reaction 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_forwardHow is the reaction quotient different from an equilibrium constant for a given reaction? Answer:arrow_forwardissue 6Choose the equilibrium in which the products are favored by a drop in pressure and the reactants favored by a drop in temperature.a) N2(g) + 3 H2(g) ⇔ 2 NH3(g) + 92.3 kJb) H2(g) + I2(g) + 51.8 kJ ⇔ 2 HI(g)c) PCl3(g) + Cl2(g) ⇔ PCl5(g) ΔH = -84.2 kJd) 2 NO2(g) ⇔ 2 NO(g) + O2(g) ΔH = +54 kJarrow_forward
- At 1130°C, the equilibrium constant (Kc) for the reaction 2H2S(g) ⇌ 2H2(g) + S2(g) is 2.25 × 10−4. If [H2S] = 4.80 × 10−3 M and [H2] = 1.40 × 10−3 M, calculate [S2]. Please write to text formet answerarrow_forwardConsider the following equilibrium: 2HF(g)⇌H2(g)+F2(g) At equilibrium, the concentration of hydrogen fluoride gas, hydrogen gas, and fluorine gas are 2.04 mol/L, 2.47 mol/L, and 1.89 mol/L. What is the value of the equilibrium constant? Answer to 3 decimal places.arrow_forwardSuppose you are given the reaction A(g) + B(g) C(g) + D(g). You have the gases A, B, C, and D at equilibrium. Upon adding gas B, the value of K: Select one: a. increases, because by adding A more products are made, increasing the product to reactant ratio b. does not change, as long as the temperature is constant c. depends on whether the reaction is endothermic or exothermic d. does not change, because A does not figure into the product to reactant ratio e. decreases, because A is a reactant so the product to reactant ratio decreasesarrow_forward
- Consider the hypothetical reaction, which has an equilibrium constant (Kp) of 16.1 when the reaction occurs at 167°C. 2 W (g) + X (g) <---> 3 Y (g) If the equilibrium partial pressure of W is 0.787 atm and that of Y is 1.65 atm, what will the equilibrium partial pressure (in atm) of X be?
