3. What mass of copper could be deposited from a copper(II) Sulphate solution using a current of 5.0 A over 100 seconds? ( F =96
arsen [322]

Mass of copper : 0.165 g

<h3>Further explanation</h3>

Given

5.0 A over 100 seconds

Required

Mass of copper

Solution

Faraday's law:

<em>The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis</em>

<em />\tt W=\dfrac{e.i.t}{96500}<em />

e = Ar / valence = eqivalent weight

i = current

t = time

W = weight

CuSO₄ ----> Cu²⁺ + SO₄²⁻

Cu ----> Cu²⁺ + 2e

e = Ar/2

= 63,5/2 = 31,75

\tt W=\dfrac{31.75\times 5\times 100}{96500}=0.165~g

The effect of a catalyst on an equilibrium is to ________. Select one: a. increase the rate of the forward reaction only b. slow
Georgia [21]

Answer:

E

Explanation:

A catalyst is a substance which alters the rate of a chemical reaction. We check for the correctness of each of the options as follows:

A. Is wrong.

A catalyst can increase the rate of the forward and backward reaction

B. Is wrong

A catalyst does not slow the reverse reaction only. This particular case is the case of a negative catalyst

C is wrong

A catalyst has no effect on the equilibrium nor the equilibrium constant

D is wrong

Catalyst has no effect on equilibrium value

E is correct

Although Catalysts has no effect on equilibrium or its constant value, it can increase the the rate at which equilibrium is achieved by speeding up the reaction through bringing down the activation energy
