Question 11.Why is a collision between molecules usually necessary for a reaction to take place?
Question 22.Suppose you were teaching a science class to middle school students. Because you want to show them an impressive chemical reaction, you decide to dissolve zinc in hydrochloric acid. You add more acid than usual and throw in pieces of zinc. What factor is not going to impact the reaction rate?
Question 33.In the rate law (Rate = k x A), what does the A stand for?
Question 44.If the exponential factor is close to 1, what is known about the activation energy and temperature?
Question 55.What molecule in our bodies is a catalyst?
Question 66.What is the frequency factor?
Question 77.What is a catalyst?
Question 88.What does the m stand for in the rate law equation?
Question 99.What does the k stand for in the rate law equation?
Question 1010.What does an increase in temperature do the reaction rate?
Question 1111.If a scientist is trying to determine the reaction order for a given reaction, then what's the most effective means to figure it out?
Question 1212.What is the rate-determining step?
Question 1313.What is the Arrhenius equation?
Question 1414.If a chemical reaction has an activation energy of 500 J, and its reactants are assembled with 250 J of energy, what will happen? Why?
Question 1515.What is a reaction mechanism?
Question 1616.In the reaction A = B, if the rate quadruples for every doubling of A, then what is the reaction order?
