Worksheet 15 b 1)When a reaction is at equilibrium, a) it has no products b) the rate of the forward reaction is equal to the rate of its reverse. c) it occurs very quickly using up all of the d) it produces the same amount of product as reactant 2) The equation: C(S)g)CO) has the following equilibrium constant expression. a) b) c) d) ICO [O,1 CO 3) in which reaction bel low are reactant concentrations greater than product concentrations? 10 KHO-2.5 x 10 Keq =[E][Hs01-6.6 x 10 HI] HF] 4) Why might increasing the concentration of a set of reactants increase the rate of reaction? a. You have increased the chances that any two reactant molecules will collide and react. b. You have increased the ratio of reactants to products c. The concentration of reactants is unrelated to the rate of reaction. d. The rate of reaction depends only on the mass of the atoms and therefore increases as you increase the mass of the reactants. None of the above e. 5) Which of the following energy diagrams represents the reaction that would proceed the fastest? lal tbl lc) 6) For the equilibrium reaction shown, determine if the reverse reaction will occur until equilibrium is reestablished: 2502(g)+O+lg) 2S0 (g) (answer yes or no) a. [SO,J is decreased c. [SO3] is decreased b. [SO:] is increased d. [O:l is increased
