At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant
ZanzabumX [31]

Answer:

0.24

Explanation:

We are given that

Rate constant for A=k=0.0180/s

Rate constant for  B,k'=0.0750/s

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

A\rightleftharpoons B

Equilibrium constant, for k=\frac{k}{k'}

Using the formula

k=\frac{0.0180}{0.0750}=0.24

Hence, the value of the equilibrium constant for the reaction

A\rightleftharpoons B at this temperature=0.24

How many grams of solution are in 75 G of NaCL
Alik [6]

Answer:The first thing you need to do here is to use the molarity of the solution to determine how many moles of sodium chloride you have in your sample.

As you know, molarity tells you the number of moles of solute, which in your case is sodium chloride, present in "1 L" of solution. This means that a "0.75 M" sodium chloride solution will contain 0.75 moles of sodium chloride for every "1 L" of solution.
