is this explaination fo rate of eraction is accurate and correact?

Question

Rate of reaction refers to the speed at which the concentration of reactant converts to a product. The formula states that [A] concentration of reactant, (-) is the concentration decreasing overtime and t represents time.
rate=-(d[A])/dt

Answer 1

Yes, the explanation of the rate of reaction and the formula for calculating it is accurate and correct. The formula rate = -(d[A])/dt represents the change in concentration of reactant [A] over time (dt) as a negative value, indicating a decrease in concentration.
