In a chemical reaction, the use of a catalyst results in a decrease in the: a) Heat of Reaction (Enthalpy) b) Potential energy of products c) Activation energY d) Amount of the reactants So. In the reaction: Pb + ZnNO, the Pb will: a) Replace the Zn and form PBNO, b) Will not replace the Zn c) Form PBNO, and dissolve in solution d) Precipitate out Jodnyes H,0 is completely S. When the equation: H; + Fe;0, balanced using smallest whole numbers, the coefficients of Hz would be: a) 1 b) 2 c) 3 d) 4 Fe + S2. What is the symbol for the element Mendelevium? a) Md b) M c) Mn d) Me 53. Which of the following is true regarding the Kinetic Molecular Theory? a) Gases consist of very small particles that are far apart from each other b) Gas particles are in constant, random motion moving in straight lines until they collide with other particles or the sides of the container c) As the temperature increases, gas particles move at a much faster rate because they are colliding with each other constantly d) All of the above statements are true regarding the Kinetic Molecular Theory S4. Given the reaction at equilibrium: N2 (g) + 3 H2 (g) will the equilibrium shift if you decrease the pressure? a) To the right b) To the left c) The reaction will be in dynamic equilibrium so the reaction will go in both directions at the → 2 NH, (g), which way same rate d) The whole reaction will explode and make a mess, so no equilibrium will be achieved
