This is because when the surface area of the Iron increases, there is more spots on the iron that is exposed to the other reactant giving the other reactant more area to collide with the iron making the reaction go faster. ]]> 2021-02-28 09:00:36 UTC https://padlet.com/syrennestudies/z0orred44evqhuf8/wish/1249563955 tamarakhoury https://padlet.com/syrennestudies/z0orred44evqhuf8/wish/1249564998 more surface area - faster reaction 
i think this because more of the iron will be exposed to the acid, causing it to react. if more Fe molecules are reacting to the acid, it will dissolve faster.  ]]> 2021-02-28 09:01:11 UTC https://padlet.com/syrennestudies/z0orred44evqhuf8/wish/1249564998 varunparekh https://padlet.com/syrennestudies/z0orred44evqhuf8/wish/1249565128 2021-02-28 09:01:15 UTC https://padlet.com/syrennestudies/z0orred44evqhuf8/wish/1249565128 https://padlet.com/syrennestudies/z0orred44evqhuf8/wish/1249565324 I think that the larger the surface area the quicker the reaction will be.

Because of the increased temperature the particles would react more frequently and quickly which will cause the reaction to speed up.

This is evident when having an increase in the surface area which leads to faster moving reactions/collisions and overall leads to a increased rate of reaction.
