Which equation is an expression of the rate law

Rate = k[A]m[B]n

What must be known for the rate constant to be calculated from the rate law

The reaction rate at known reactant concentrations.

Which of the following best describes a neutralization reaction

Answer this question… Which of the following best describes a neutralization reaction? A. Acid + base H+ + OH- B. Acid + base salt + water C. Acid + base metal + nonmetal D. Acid + base H2O + H3O+

What are m and n in the rate law equation

They are experimentally determined exponents

Which of the following is an example of a conjugate acid-base pair

H2S and HS-

Which of the following acts as a catalyst in catalytic converters

Metal

What is true of a Lewis base

A Lewis base donates electron pairs.

What is the rate constant of a reaction if rate 1 10-2 molLs A is 2 M B is 3 M m 2 and n 1

4.5 (moI/L)/s -apex

Which has the largest rate constant k

Dynamite exploding

What information does an energy diagram give

It shows the energy requirements needed in order for a reaction to occur.

What is the rate of a reaction if the value of k is A and B are each 2 M

24

Scientists design drugs alongside which type of engineers

chemical

What equation shows how rate depends on concentrations of reactions

The equation is called the rate law equation. For the reaction aA+bB =>cC+dD the rate law would be rate = k[A]^m[B]^n where k is the rate constant and m and n are the "order" with respect to each reactant. m and n must be determined experimentally and may or may not be the same as the coefficients a and b.
