2. Utilize your knowledge of reaction rates, collision theory and activation energy to explain why concentrated solutions of acids are more reactive than dilute solutions of acids?
Use collision theory to explain why reaction rates depend on the concentration of the reactants and on the temperature of the reaction mix. PLEASE EXPLAIN.
Question 2 of 10 Which of the following statements concerning the collision theory of reaction rates is correct? 1. The activation energy is the difference between the EAHf° (products) and EAHf° (reactants). 2. The activation energy for the forward reaction is the negative of the activation energy for the reverse reaction. 3. The pre-exponential or frequency factor in the Arrhenius equation is a measure of the fraction of reactant molecules having sufficient energy to react. 4. The activation energy of...

1) If the activation energy of a reaction is 34 kJ/mol and the amount of energy provided by the collision of reactants (in the correct orientation) is 28 kl/mol, will a reaction occur? Explain your answer. What could you do to attempt to get this reaction to occur? 2) Using the reaction below, explain what would occur to equilibrium position and why FeCl,(ag)+3KSCN(aq)Fe(SCN), (ag)+3KC[ (aq) + heat A. Performing the reaction in a freezer (ie. removing heat). B. Adding more...
There are several theories that try to explain why we sleep, the Information Consolidation theory states that we sleep in order to: A. To rest and conserve energy B. Regenerate and repair the body C. Organize information and store long-term memories D. Keep safe from predators when we are most vulnerable
Chemical reaction rates slow down as the temperature is decreased. This is why we put food in the refrigerator to preserve it. By thinking about matter on the microscopic (molecule) level explain why this happens
Dr. Megehee Which statement is false concerning collision theory and reaction rates? A) In most reactions, when reactants collide they must be in B) The the proper orientation. rate of a reaction is directly proportional to the number of effective collisions Generally, reaction rates increase by a factor of 10 for each 10 degree increase in Usually, reactions having a low Ea occur faster than ones having a high Ea- Not all collisions are effective.
