Chemistry · Rate of a chemical reaction, factors affecting the rate of reactions: concentration, temperature, pressure and catalyst
The term -dx/dt in the rate expression refers to:
The term -dx/dt in the rate expression refers to:
- A. The concentration of the reactants
- B. Increase in the concentration of the reactants
- C. The instantaneous rate of the reaction
- D. The average rate of the reaction
Step-by-step solution
In chemical kinetics, the term -dx/dt represents the derivative of concentration with respect to time, which gives the rate at a specific instant. The negative sign indicates the consumption of reactants, so it is the instantaneous rate of reaction, not the average rate.
