5. Consider the generic reaction shown below in which reactant A is converted to product B. A pure sample of reactant A is allowed to reach equilibrium. The concentrations of both A and B were monitored during this process and plotted below as a function of time. A(8)=B (8) concentration time a. Based on these data, is the value of Key for this reaction greater than or less than 1? Briefly explain how you can tell. b. The reaction is...

Part 1.) Select all of the correct statements about reaction rates from the choices below. 1. The lower the rate of a reaction the longer it takes to reach completion. 2. As a reaction progresses its rate goes up. 3. Catalysts decrease reaction rates. 4. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. 5. Reaction rates increase as concentrations of homogeneous catalysts increase. 6. The higher the rate of a...

REACTION RATES The After Thought 1. Cross out the incorrect statement(s) dealing with factors affecting the rate of a chemical reaction. The rate of a chemical reaction increases: - with increasing concentration of a reactant since the number of collisions increases - with decreasing temperature since the activation energy is reduced - by pulverizing a reacting solid because its exposed surface area increases - with the addition of a...
