Hypothesis: If warm temperatures increase chemical reactions then the glow stick placed in warm water will shine brighter than the one in cold water because molecules will collide and produce a chemical reaction faster in warmer water. Materials: 2 glow sticks, 2 -250ml plastic beakers, water, ...
Steps to Balancing Equations There are four basic steps to balancing a chemical equation. Write the correct formula for the reactants and the products. Find the number of atoms for each element on the left side. Compare those against the number of the atoms of the same element on the right...

Thus , in general, for any number of reactions in series it is the slowest step that has the greatest influence on the overall reaction rate ;;;As may be expected, the value of k1 and k2 also govern the location and maximum concentration of P. This may be found by differentiating Eq....
