Reaction rate means...

amount of product formed

speed of reaction

concentration of reacting particles

combining reactants with products

To slow down a chemical reaction you will do one of the following:

Place the reactants in hot water

Place the products in ice bath

Place the reactants in a ice bath

Keep stirring the reactants with a stirring rod

Which of the following increase the reaction rate?

less surface area

lower temperature

increasing pressure

increased concentration

A catalyst works by

changing the order of the reaction

increasing the temperature

lowering the activation energy

making the activated complex

The rate of a chemical reaction is NOT affected by which of the following:

temperature

concentration

particle size (surface area)

All of these affect reaction rates

A possible rate law for a third overall order of a reaction is __________________

Rate = k [A]²[B]²

Rate = k [A][B]³

Rate = k [A]³ [B]

Rate = k [A]²[B]

If the concentration of [A] is doubled, and the rate of the reaction also doubles. What reaction order is [A]?

Zero-order

First-order

Second-order

Triple-order

If we double the concentration of a reactant and the rate quadruples, what rate order is this?

first order

second order

third order

eighth order

What is the overall rate order of this chemical rate law:

Rate = k

zero-order

first-order

second-order

third-order

10.

Look at the rate equation: Rate=k[H₂O][HCl]

What is the overall order of the reaction?

first-order

second-order

third-order

fourth-order

11.

Which trials would be used to measure the rate exponent for A?

trials 1 and 2

trials 1 and 3

trials 2 and 3

12.

For a reaction 2A + B --> 2C, with the rate equation:

Rate = k [A]²[B]

The order with respect to A is 1 and the order overall is 1

The order with respect to A is 2 and the order overall is 2

The order with respect to A is 2 and the order overall is 3

The order with respect to B is 2 and the order overall is 3

The order with respect to B is 2 and the order overall is 2

13.

The only factor that can change the value of k is:

concentration

a catalyst

surface area

temperature
