Does this graph show an endothermic of exothermic reaction? (WILL GIVE BRAINLIEST)

1. endothermic, because the products are at a lower energy state in the reactants
2. endothermic, because it takes a lot of energy to cause the reaction to occur
3. exothermic, because the products are at a lower energy state in the reactants
4. exothermic, because it takes a lot of energy to cause the reaction to occur

3. exothermic, because the products are at a lower energy state in the reactants

Explanation:

It is also because the average enthalpy is negative.

since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
