Chemical equations do not tell about the _ because of certain limitations:
Correct answer: D. All
- A. Rate of reaction
- B. Physical states of reactants and products.
- C. Conditions
- D. All
Explanation
Chemical equations involve the elements involved in a reaction, the number of molecules of the elements, the state symbols. It has specific limitations and does not show the rate of reaction and condition required for reaction to occur. Chemical equations give information about physical states of reactants and products. The terms like pressure, temperature and volume also affect the chemical reaction. The rate of a reaction cannot be known by looking at chemical reactions

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
