Catalysts are substances that ____________ the rate of a chemical reaction
ss7ja [257]

Catalysts are substances that speed up the rate of a chemical reaction. It is important to know that reacting species must first possess a minimum amount of energy equal to the activation energy for the reaction to proceed. The catalyst works in a way that lowers the activation energy required for the reaction to proceed. In this way, the reaction occurs at a faster rate than without a catalyst. Catalysts do not react with the chemical species in the reaction, thus, they are not consumed. However, over time, catalysts tend to degrade and their function is also reduced. When this happens, new catalysts replace the poisoned ones. Catalysts are widely used today since they bring an increase in the production rate of commercial chemicals.

Which atom attracts electrons more strongly?
lesya [120]
Bromine attracts electrons more strongly. Cesium is In fact the least electro negative element.

Sodium is more likely to lose an electron because is is less electro negative. Strong electronegativity make the element want more electrons. Sodium has loose electrons with a lower electronegativity so it gives it up easier.
