At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant of 0.0180 s − 1 . The reverse reaction is first order in B and the rate constant is 0.0750 s − 1 . What is the value of the equilibrium constant for the reaction A − ⇀ ↽ − B at this temperature?

0.24

Explanation:

We are given that

Rate constant for A=

Rate constant for  B,k'=0.0750/s

We have to find the value of equilibrium constant for the reaction

Equilibrium constant, for k=

Using the formula

Hence, the value of the equilibrium constant for the reaction

at this temperature=0.24

pure substance: iron,copper

impure substance: water,charcoal

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
