A reaction that involves reagent X as the limiting reagent is begun with an initial concentration of 0.732-M X. The reaction rea
katovenus [111]

Answer:

The answer to the question is 0.0122 m/s

Explanation:

The rate of a reaction is the measure of the change in concentration of a reagent within a specific time frame. Reaction rate of a substance can be calculated by finding the division of the concentration change of the substance and the time required to undergo the change in concentration.

Average reaction rate \frac{Change in the moles count of X}{Change in time} =

The initial number of moles of X = 0.732 moles and final number of moles of X  = 0 moles and the time it took to effect the change = 60s

then the rate of reaction = \frac{0.732}{60} = 0. 0122 moles per second

the rate of the reaction involving X = 0.0122 m/s

nika2105 [10]

Answer:

3.50*10^-11 mol3 dm-9

Explanation:

A silver rod and a SHE are dipped into a saturated aqueous solution of silver oxalate, Ag2C2O4, at 25°C. The measured potential difference between the rod and the SHE is 0.5812 V, the rod being positive. Calculate the solubility product constant for silver oxalate.

Ag2C2O4 -->  2Ag+  +  C2O4 2-

So Ksp = [Ag+]^2 * [C2O42-]

In 1 L, 2.06*10^-4 mol of silver oxalate dissolve, giving, the same number of mol of oxalate ions, and twice the number of mol (4.12*10^-4) of silver ions.

So Ksp = (4.12*10^-4)^2 * (2.06*10^-4)

= 3.50*10^-11 mol3 dm-9
