Chemistry · Rate of a chemical reaction, factors affecting the rate of reactions: concentration, temperature, pressure and catalyst
The minus in }{d t} \) indicates the concentration of the time. The rate of a re
The minus \( \operatorname{sign} \) in \( r a t e=-\frac{d[A]}{d t} \) indicates the concentration of the time. The rate of a reaction is always quantity. The rate of reaction increases with concentration of reactants. The blanks in the question corresponds to:
- A. decrease, products, positive, increase
- B. increase, reactants, negative, decrease
- C. decrease, reactants, positive, increase
- D. increase, products, positive, increase
Step-by-step solution
The minus sign in rate = -d[A]/dt indicates the decrease in concentration of the reactants with time because d[A]/dt is negative. The rate of a reaction is always positive. Increasing the concentration of reactants increases the rate of reaction.
