Question

The rate of a chemical reaction depends upon:

• A. pressure
• B. temperature
• C. concentration
• D. catalyst

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A pressure
B temperature
C catalyst
D concentration

The rate of a chemical reaction depends on factors that affect whether reactants can collide with sufficient energy for reaction to occur. Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, pressure, the physical state of reactants and their dispersion, the solvent and the presence of a catalyst.
