How many grams of copper will be plated out by a current of 2.3 a applied for 35 minutes to a 0.50 m solution of copper (ii) sul

kumpel [21]

When the magnitude of the charge Q = I*T

when we have I current = 2.3

and T = 35 min * 60 = 2100 s

by substitution:

∴ Q = 2.3 * 2100

= 4830 C

according to this reaction equation:

Cu2+ + 2e-  → Cu

we can see that 1 mol Cu2+ need 2 mol e- to produce Cu

mol of electron e- = Q / faraday's constant

= 4830 / 96485

= 0.05 mol

when 1 mol Cu2+  → 2 mol e-

??   ← 0.05 mol

∴ moles Cu2+ = 0.05 /2 = 0.025 mol

∴ mass Cu2+ = moles Cu2+ * molar mass Cu2+

= 0.025 * 64

= 1.6 g

The rate constants of some reactions double with every 10 degree rise in temperature. Assume that a reaction takes place at 271

AfilCa [17]

Answer : The activation energy for the reaction is, 119.7 J

Explanation :

According to the Arrhenius equation,

$K=A\times e^{\frac{-Ea}{RT}}$

or,

$\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]$

where,

$K_1$ = rate constant at 271 K

$K_2$ = rate constant at 281 K = $2K_1$

$Ea$ = activation energy for the reaction = ?

R = gas constant = 8.314 J/mole.K

$T_1$ = initial temperature = 271 K

$T_2$ = final temperature = 281 K

Now put all the given values in this formula, we get:

$\log (\frac{2K_1}{K_1})=\frac{Ea}{2.303\times 8.314J/mole.K}[\frac{1}{271K}-\frac{1}{281K}]$

$Ea=119.7J$

Therefore, the activation energy for the reaction is, 119.7 J

The acceleration of a sprinter is 10 m/s2. The force exerted on the starting blocks is 650 N. What is the mass of the sprinter?

jek_recluse [69]

The relation between force, mass of an object and its acceleration is given by following equation

F = mass of object X acceleration

The unit of Force is Newton (N)

unit of acceleration is ms⁻²

unit of mass if Kg

[all these are SI units]

Mass of object = $\frac{Force}{acceleration}$

mass of sprinter = $\frac{650}{10}=65kg$
