Will mark brainliest in the diagram, the black line represents the concentration of a reactant and the green line represents the concentration of a product.

which statement best describes the reaction rate?

the reactants maintain an constant concentration in the first half of the reaction.

at the end of the reaction, both product and reactants are of an equal concentration.

the product maintains an constant concentration in the first half of the reaction.

at the end of the reaction, both product and reactants are of a constant concentration.

Explanation:

took the test

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
