the combustion of 0.1240 kg of propane in the presence of excess oxygen produces 0.3110kg of carbon dioxide what is the limittin
mote1985 [20]

Answer:

Propane

Explanation:

From the question given, we were told that 0.1240 kg of propane reacted with excess oxygen to produce 0.3110kg of carbon dioxide.

Since the reaction took place in the presence of excess oxygen, therefore, propane is the limiting reactant as all of it is used up in the presence of excess oxygen.

Calculate the cell potential, the equilibrium constant, and the free energy change for
Tresset [83]

Answer:

Explanation:

Ba(s) + Mn²⁺ (aq,1M)  →      Ba²⁺ (aq,1M) + Mn(s)

Ba⁺²(aq) +2e →  Ba(s) ,  E° =  −2.90 V  

Mn⁺²(aq) +2e → Mn(s),  E⁰  =0.80 V

Anode reaction :

Ba(s)  →  Ba⁺²(aq) +2e        E° =  −2.90 V  

Cathode reaction :

Mn⁺²(aq) +2e → Mn(s)          E⁰  =0.80 V

Cell potential = Ecathode  - Eanode

Ecell  = .80 - ( - 2.90 )

Ecell = 3.7 V .

equilibrium constant ( K ) :

Ecell = .059 log K  / n

n = 2

3.7  = .059 log K  / 2

log K = 125.42

K = 2.63 x 10¹²⁵ .

Free energy change :

ΔG = - n F Ecell

= - 2 x 96500 x 3.7

= 714100 J

= 7.141 x 10⁵ J .
