Acatalyst increases the rate of a reaction without being consumed. it accomplishes this by providing another mechanism that has a lower activation energy. true or false?

True.

Explanation:

Hello,

Catalysis states that a catalyst is consumed but subsequently regenerated via inner mechanisms that allows it to achieve it. Besides, it is true that the inner mechanism has a lower activation energy which allows the reaction to be rapidly carried out in comparison with the catalystless chemical reaction.

Best regards.

right

explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
