- RATE OF REACTION OF MAGNESIUM RIBBON WITH HYDROLIC ACID CONCLUSION -
I can conclude that if you double the concentration of the acid the reaction rate would
also double, this is because the ions are closer together in a concentrated solution. ... The more often they collide, the
higher the ... - Rates of reaction - ...
There are four factors that affect the rate of reaction:
1 - Temperature. ... They will collide more frequently increasing the rate of reaction. ...
Catalyst:
Addition of a catalyst increases the rate of r...
