What is the formula used to calculate the rate of a reaction?

What is the integrated rate law for a zero order reaction?

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the order of a reaction with respect to a reactant?

Back

The order of a reaction with respect to a reactant is the exponent to which the concentration of that reactant is raised in the rate law.

Front

What is the overall order of a reaction?

Back

The overall order of a reaction is the sum of the orders with respect to each reactant in the rate law.

Front

What is the rate constant (k)?

Back

The rate constant (k) is a proportionality factor that relates the rate of a reaction to the concentrations of the reactants.

Front

What is the difference between first order and second order reactions?

Back

In a first order reaction, the rate is directly proportional to the concentration of one reactant. In a second order reaction, the rate is proportional to the square of the concentration of one reactant or the product of the concentrations of two reactants.

Front

What is the half-life of a reaction?

Back

The half-life of a reaction is the time required for the concentration of a reactant to decrease to half of its initial concentration.

Front

What is the effect of temperature on reaction rate?

Back

Increasing the temperature generally increases the reaction rate because it increases the kinetic energy of the molecules, leading to more frequent and effective collisions.

Front

What is the collision theory?

Back

Collision theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.
