The decomposition of NH,HS is endothermic: NH,HS (s) NH3 (g) + H,S (g) Which change to an equilibrium mixture of this reaction results in the formation of more H,S? O a decrease in pressure an increase in temperature an increase in the amount of NH4HS O a decrease in the volume of the reaction vessel (at constant temperature)
Consider the following system at equilibrium at 698 K. 2 HI(g)→ H₂(g) + I₂ (9) Use the References to access importa When some HI(g) is removed from the equilibrium system at constant temperature, the reaction must O run in the forward direction to reestablish equilibrium. O run in the reverse direction to reestablish equilibrium. O remain the same. It is already at equilibrium. The concentration of H₂ will O increase. O decrease. O remain the same.
The reaction below was allowed to react at 375 degrees Celcius until it formed an equilibrium. At equilibrium, the 16.2 L container was found to contain 1.9 mol SiF4, 1.1 mol H2O, 3.5 mol SiO2, and 2.9 mol HF. What is the Kc of the reaction at this temperature? SiF4 (g) + 2H2O (g) <--> SiO2 (s) + 4HF(g)
For any reversible reaction containing a double arrow such as: Reactants Products the statement "equilibrium shifts to the right" means: The reaction can only go in the forward direction. The reaction can only go in the reverse direction. A stress will cause a portion of reactants to disappear and some additional veadde on snpoud A stress will cause a portion of products to disappear and some additional reactants to appear
When a reaction's reaction quotient is smaller than its equilibrium constant, what does this indicate about the reaction's equilibrium? The reaction must proceed in the reverse direction to return to equilibrium. The reaction is at equilibrium and will not change. O The reaction must proceed in the forward direction to return to equilibrium. O Nothing. There is no relationship between the reaction quotient and equilibrium constant.
