Question

In a reaction that increased in rate due to an increase in concentration, the increase in rate was due to a. the heat generated by increasing the concentration. b. the increased number of molecular collisions. c. the increased energy of activation d. all of these choices are correct. Question 5 A reaction that is endothermic presents an energy diagram that a. has a high energy of activation, but has products just barely lower in energy than the reactants. b. looks like an energy diagram for an exothermic reaction, but with a higher energy of activation requirement. . has no energy of activation, but has products that are significantly lower in energy than the reactants. d. has products that have more energy than the reactants and will generally absorb energy.

Explanation / Answer

1)

As there is more concentration for solution, the number of reactant in solution increases

This increases the number of collision and hence increases the probability of effective collision thus increasing the rate

Answer: b

5)

The reaction is endothermic

That means energy is being absorbed

So, product will have more energy that reactant

Answer: d
