Describe ways to mesure rate of reaction.

1)Mesuring mass change -effective when carbon dioxide is produced as it leaves reaction container -innefective for gases with small rfm like hydrogen 2)Mesuring volume change -useful when gas leaves container - mesured in gas syringe or burette or mesuring cylinder 3)Graph -mass/volume of product on Y axis Time on X axis -gradient equal to rate of reaction (steep gradient fast reaction)
