What is meant by the rate of reaction

The rate of reaction refers to the speed at which a reaction proceeds.

What is the equation for reaction rate

For a reaction whose slowest step is

mX + nY ----> aXY

rate = k * [X]m * [Y]n

where k is the rate constant; brackets represent concentrations; m and n are exponents on the concentrations of X and Y, respectively

What does the rate law use to determine the rate of a reaction

The rate of a reaction is calculated using the concentrations of reactants.

What does it mean if keq1

I suspect it could be " k eq 1" , or "k =1".

Which of the following conclusions can be drawn from the curves in the energy diagram

. The reaction represented by curve B will go faster than the curve A reaction.

What causes the reaction rate to decrease as the reaction progresses

The concentration of the reactants decreases.

Which of the following Ka values represent the weakest acid

Ka= 1.62 x 10-12

What increases the chance of reaction when two molecules collide

increasing the concentration in the molecue

A scientist has just developed a composite drug to fight seasonal allergies. What is the next step in the engineering process before the drug is released

Testing the composite drug in a trial run.

The process of using computers and robots to conduct thousands of tests to determine the interaction between different compounds and a disease is called what
