How would a catalyst change the reaction energy diagram
Answer

a catalyst speeds up the reaction

A catalyst can change the reaction energy diagram is that a catalyst speeds up the reaction.

a salt and water are formed

What would cause your car to make a grinding sound while traveling at speeds under 35 mph

Are we talking about the front wheels or the rear? Have you checked your wheel bearings?

What happens in an acid-base reaction according to the Arrhenius definition

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-

How does increasing the temperature affect collisions

It increases the number of high-energy collisions

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.

Which has the largest rate constant k

Dynamite exploding

What is the sugar pill called

Placebo

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.
