3. If the equilibrium constant for a chemical reaction decreases as the temperature is increases from...
The equilibrium constant for a given reaction a. always increases with temperature. b. increases with temperature for endothermic reactions only. c. increases with temperature for exothermic reactions only. d. does not change with temperature. e. always decreases with temperature.
All questions are true or false A catalyst changes both the equilibrium constant and the rate of a chemical equilibrium. j. Ifthe temperature of a chemical equilibrium is increased, the reaction will shift in a direction that will lead to the consumption of some of the extra heat. An increase in temperature favors an endothermic reaction over an exothermic reaction. k. nundifis Is ined If a chemical equilibrium is exothermic in the forward direction, it is also exothermic in the...
QUESTION 4 In general, as the temperature increases, the equilibrium constant, Kea -1 Increases only for an endothermic reaction Increases regardless of whether it is an endothermic or exothermic reaction Increases only for an exothermic reaction Is constant regardless of whether it is an endothermic or exothermic reaction Is constant only for nonspontancous reactions QUESTION 5 The equation of the line for the graph obtained for a thermodynamic experiment is y= (13111 K)x-29.655. Use this to answer the next two...
Question 28 (5 points) For a particular reaction, increasing the temperature of the reaction at constant pressure and volume increased the formation of the product. Which of the following is true for the reaction? The reaction is exothermic. Increasing the temperature always increases the product formation, so you can't tell if it is endothermic or exothermic. The reaction is endothermic. Temperature changes do not affect the equilibrium.
17. By increasing the temperature at an equilibrium reaction: a. the reaction will move towards the endothermic reaction b. the reaction speed constant is reduced c. the reaction is accelerated as the number of sites where the reaction can occur increases d. the exothermic reaction is favored
5) For a particular chemical reaction it is found that the value for the equilibrium constant for the reaction decreases as temperature increases. Based on this we can conclude a) AH> 0 b) AH 0 c) ASºren > 0 d) AS p < 0 e) AGO

Answer the questions about the following reaction below. The equilibrium constant for the decomposition of PCls at 250°C is 0.041 ΔH is positive; reactants and products are gases at 250°C. Refer to your textbook. 1. Is the reaction above exothermic or endothermic? 2. What happens to the concentrations of PCls and Cl if more PCls is added once the reaction reaches equilibrium? (increases, decreases) PC1s Cl2 3. What happens to the moles of PCIs, PCls and Cl in the container...
For the following reaction, the gases A, B, and C are at equilibrium. If additional amount of gas A is introduced, the equilibrium constant K: A(g) + B(g) C(g) a) Increases because by adding A, more products are made and the product to reactant ratio increases. b) Decrease because A is a reactant so the product to reactant ratio decreases c) Does not change because [B] and [C] do not change. d) Does not change as long as the temperature...
The Temperature Dependence of Chemical Equilibrium For an equilibrium reaction: A + B C + D Given the above relationship, use the graph to identify which of the following statements are "true" or "false" in this specific case. All statements refer to the forward reaction (proceeding left to right, as given) corresponding to the equilibrium constant K. 1)The reaction is spontaneous at the highest temperatures but not at lower temperatures. 2)deltaS° for the reaction is negative. 3)deltaG° is negative at...
