What determines the rate of a reaction mechanism?

Back

The slow step determines the rate of a reaction mechanism.

Front

What is NOT a way to speed up a reaction?

Back

Decreasing the pressure is NOT a way to speed up a reaction.

Front

If you quadruple the concentration and the rate quadruples, what order is this reaction?

Back

This reaction is first order.

Front

What is the rate law for the reaction with the slow elementary step A --> B + C?

Back

The rate law is rate = k[A].

Front

What order is represented by a graph that is a downward curve?

Back

The graph represents a second order reaction.

Front

Define a catalyst.

Back

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

Front

What effect does increasing the concentration of reactants have on the reaction rate?

Back

Increasing the concentration of reactants generally increases the reaction rate.

Front

What is the relationship between reaction rate and surface area of a solid reactant?

Back

Increasing the surface area of a solid reactant increases the reaction rate.

Front

What is the effect of temperature on reaction rates?

Back

Increasing the temperature typically increases the reaction rate.

Front

Define the term 'rate law'.

Back

The rate law is an equation that relates the rate of a reaction to the concentration of reactants.
