Click on the graph to show how rate of reaction is usually related to activation energy Which one

Graph 3

Explanation:

Activation energy is the level of energy required by a chemical reaction for the reaction to proceed.

A higher Activation energy will translate to a lower reaction rate because less molecules will be able to achieve this required energy needed for them to react. A lower activation energy however will enable a faster reaction time because more molecules will achieve the required energy.

Higher Activation energy = Lower Reaction rate

Lower Activation energy = Higher reaction rate

This is what Graph 3 shows so it is correct.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
