Introduction to Chemistry
- Apply collision theory to explain why increasing the concentration of a reactant usually increases the reaction rate.arrow_forwardApply collision theory to explain why powdered zinc reacts to form hydrogen gas faster than large pieces of zinc when both are placed in hydrochloric acid solution.arrow_forwardWhat happens to the reactants in an ineffective molecular collision?arrow_forward
- . Account for the increase in reaction rate brought about by a catalyst.arrow_forwarda What happens to a reaction rate as temperature drops? Give two explanations for the change. State which one is more important and explain why. b How does a catalyst affect reaction rates? c Compare reaction rates when a given reactant concentration is high with the rate when the concentration is low. Explain the difference.arrow_forwardClassify each of the following statements as true or false. aSome equilibria depend on a steady supply of a reactant in order to maintain the equilibrium. bBoth forward and reverse reactions continue after equilibrium is reached. cEvery time reactant molecules collide, there is a reaction. dPotential energy during a collision is greater than potential energy before or after the collision. eThe properties of a transition state are between those of the reactants and products. fActivation energy is positive for both the forward and reverse reactions. gKinetic energy is changed to potential energy during a collision. hAn increase in temperature speeds the forward reaction but slows the reverse reaction. iA catalyst changes the steps by which a reaction is completed. jAn increase in concentration of a substance on the right-hand side of an equation speeds the reverse reaction rate. kAn increase in the concentration of a substance in an equilibrium increases the reaction rate in which the substance is a product. lReducing the volume of a gaseous equilibrium shifts the equilibrium in the direction of fewer gaseous molecules. mRaising temperature results in a shift in the forward direction of an endothermic equilibrium. nThe value of an equilibrium constant depends on temperature. oA large K indicates that an equilibrium is favored in the reverse direction.arrow_forward
