Question

which of the following which of the following potential energy diagrams represent an endothermic reaction? chothe fooing poatential enery Reaction Zoordinate Reactionboordinate B Diagram B because the p Diagram B because the reactants are at higher energy that the products. Diagram B because the products are at higher energy than the reactants. C Diagram A because the reactants are at higher energy that the products. D Diagram A because the products are at higher energy than the reactants For questions 18-20 consider the free energy diagram for the hypothetical reaction X # Y. Note that the x axis gives the concentrations of X and Y at different points as the reaction goes from left to right (pure X to pure Y). 18)Which point on the curve represents the point at Ill which the reaction is at equilibrium? A The point labelled I B The point labelled II C The point labelled IV D The point labelled V E The point labelled VI 19)Which one of the following statements about this reaction at the point labelled II is correct? a The reaction will move spontaneously in the forwards direction (X Y) until it reaches b, The reaction will move spontaneously in the forwards direction (X Y) until it reaches c The reaction will move spontaneously in the backwards direction (Y X) until it reaches d· The reaction will move spontaneously in the backwards direction (Y X) until it reaches the point labelled IV. the point labelled VI. the point labelled I. the point labelled II 20)Use the curve to determine the value of the equilibrium constant for this reaction A 0.25 B 0.67 c 1.0 D 1.5

Explanation / Answer

17)

for endothermic reaction, energy is added

so product should have higher energy as compared to reactants

Diagram A represent endothermic process
