The rate is a mathematical relationship obtained by comparing reaction rate with reactant concentrations.
CBr4 is a symmetric tetrahedral molecule so it will be non-polar.
Out of the options, the best indicator is a color change since it is the only one that can't really be blamed on a physical change. you will eventually notice that during qualitative labs and some quantitative labs, usually the thing that you are looking for is either color change or the production of a precipitate to indicate the presence of a chemical reaction
Answer: is C
Explanation:
Both the atomic mass and the atomic number increase from left to right
