Answer needed asap.

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?

a. higher temperature increases reaction rates for both endothermic and exothermic reactions.

b. an endothermic reaction would not speed up at higher temperatures.

c. 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.

The organism shown is a free-living one that is anchored to the bottom of ponds and streams during one stage of its life cycle what is the common name for the group to which this organism belong

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
