PLZZ HELP ITS TIMED Burning wood is a chemical reaction that requires oxygen. Sometimes people start a fire by lighting paper with a match and then blowing gently on the lit paper, Blowing on
the lit paper helps the reaction rate, or fire, go faster. Blowing on the lit paper moves more ait, which contains oxygen, over the reaction site

Which statement is true about why this works?

Blowing on fire reduces the temperature and increases reaction rate

Blowing on fire increases the concentration of oxygen and increases the reaction rate

Blowing on fire increases the temperature and increases reaction rate

Blowing on fire decreases the concentration of oxygen and increases the reaction rate
