A student performs a reaction twice. In the second trial, he increases the temperature of the reaction and notes that the reaction happens more quickly. The student concludes that this means the reaction was endothermic. What is wrong with
the student's reasoning? (2 points)
O
a
Higher temperature increases reaction rates for both endothermic and exothermic reactions.
b
An endothermic reaction would not speed up at higher temperatures.
с
Temperature does not affect the rate of a reaction.
d
The higher temperature in the second trial actually lowered the activation energy of the reaction.

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
