How does increasing the temperature affect a reaction
🔄 Click to see definition
Definition1/14
Increasing temperature affects a reaction in two ways:
1) at higher temperatures the molecules are moving around faster
and collisions and reactions are more frequent, so the reaction -
both forward and reverse - speed up.
2) at higher temperatures, the equilibrium state will shift. In
some cases it will shift the equilibrium towards the product. In
other cases, it will shift it back towards the reactants.
