Consider the following reaction and predict the new rate of the reaction if the concentration of A is doubled and the concentration of B was quadrupled.  The new rate will be how many times greater than the original rate?

The rate of reaction was measured during a chemical reaction. After the first 3 seconds, the rate of reaction was 1.8 x10−6 M/s. Which of the following would you expect after another 3 seconds?  The rate would be lower, and the concentration of products would be higher.  The rate would be lower, and the concentration of products would be lower.  The rate would be higher, and the concentration of products would be higher.  The rate would be higher, and the concentration of products would be lower

Which statement is INCORRECT with regard to kinetics? Each 10° C rise in temperature approximately doubles the rate of a reaction. The rate is expressed as the change in concentration per the change in time. The rate of reaction is always expressed as a positive value. The presence of a catalyst decreases the rate of reaction by lowering the E, of the reaction. The effect that changing the concentration of a reactent has on the rate of a reaction must be determined experimentally.

For a given reaction, how will the rate constant (k) change with temperature? The rate constant will be the same at all temperatures. The rate constant will increase as temperature increases. The rate constant will decrease as temperature increases. How the rate constant changes will depend on what the specific reaction is.

Classify the actions based on how they could affect a reaction rate. Rate increases Rate decreases Rate is unaffected Answer Bank decrease the concentration of a reactant decrease the surface area of a solid reactant increase the temperature add a catalyst

Some measurements of the initial rate of a certain reaction are given in the table below. [N-] [H.] initial rate of reaction 2.27 M 1.81 M 16.0M/s 2.27 M 0.429 M 0.899 M/s 9.19 M 1.81 M 262. M/s Use this information to write a rate law for this reaction, and calculate the value of the rate constant k. Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol.

At a given temperature, a reaction has a rate constant of  5.83 x 10 -5 s -1. If the starting concentration is 2.65 Molar, the initial instantaneous rate will be At a given temperature, a reaction has a rate constant of  5.83 x 10 -5 s -1. If the starting concentration is 2.65 Molar, the initial instantaneous rate will be 6.91 x 10 -7 M/s 2.00 M/s 4.28  x 10 -1  M/s 0.962 M/s 7.15  x 10 -1   M/s 8.93 x 10 -3  M/s 1.54 x 10 -4  M/s 1.56 M/s

The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product.    Using the internet , research the two factors below that affect the rate of a chemical reaction.    1)Temperature  ( add an example and be very detailed add graphs as well)   2) Presence of a catalyst.    ( add an example and be very detailed add graphs as well)    Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!
