At a given temperature, the elementary reaction a − ⇀ ↽ − b , in the forward direction, is first order in a with a rate constant of 0.0340 s − 1 . the reverse reaction is first order in b and the rate constant is 0.0740 s − 1 . what is the value of the equilibrium constant for the reaction a − ⇀ ↽ − b at this temperature?

0.4595 is the value of the equilibrium constant for the reaction.

Explanation:

A ⇆ B

The forward direction, is first order in A with a rate constant = K =

The rate of forward reaction = R

The backward direction, is first order in A with a rate constant = K' =

The rate of backward reaction = R'

At equilibrium rate of forward reaction are equal to the rate of backward reaction.

R = R'

0.4595 is the value of the equilibrium constant for the reaction.

the answer is   c.) 1575 j.

explanation:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
