Catalysts that are called "enzymes".
Enzymes
Chemical reactions occur because reactants are trying to become energetically more stable
We apply the term chemical weathering to the (chemical) reactions that occur and dissolve minerals in rock.
Chemical weathering occurs more rapidly in a hot, wet climate because chemical reactions speed up with increased temperature.
Some chemical reactions produce heat, these are called exothermic
Temperature is another significant factor in chemical weathering because it influences the rate at which chemical interactions occur. Chemical reactions rates increase as temperatures increases. With all other factors being equal, the rate of chemical weathering reactions doubles with each 10C increase in temperature.
A catalyst helps chemical reactions occur.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell.
Nope!
These are not chemical reactions but thermonuclear reactions.
Cooking and burning involve chemical reactions.
No, chemical reactions can be endothermic or exothermic.
In a vacuum
We call this collection of chemical reactions metabolic reactions or metabolism.
Chemical reactions occcur metabolic reactions occur

how does enzymes in your body make chemical reactions occur at safe temperature
