A cell has a standard emf of + 0.135 v at 298 k. part a what is the value of the equilibrium constant for the cell reaction if n

Irina-Kira [14]

To look for the value of the equilibrium constant for the cell where n=1, it is computed by:
Eo = RT / nF * ln(K)
(Eo * nF) /RT = ln(K)
(0.135 * 1mol* e- * 9.65E4C/mol*e) / (8.314J / molK * 298K) = ln(K)
10.52 = lnK
e^10.52 = e ^ lnK
K = e ^263/25
K = 37049.12 is the answer.

Calculate the pH of a solution that is 0.113 M HCI.

Alex Ar [27]

Simplified concentration

$\\ \rm\Rrightarrow 1.13\times 10^{-2}M$

Now

$\\ \rm\Rrightarrow pH=-log[H^+]$

$\\ \rm\Rrightarrow pH=-log(1.13\times 10^{-2})$

$\\ \rm\Rrightarrow pH=-log1.13-log10^{-2}$

$\\ \rm\Rrightarrow pH=-0.05+2$

$\\ \rm\Rrightarrow pH=1.95$

For some transformation having kinetics that obey the Avrami equation (Equation 11.17), the parameter n is known to have a value

Alex787 [66]

Answer:

t ≈ 235.47 secs

Explanation:

<u>Calculate how long it will take the transformation to go to 88% completion</u>

Given that Avrami equation ( <em>y </em>)= 1 - exp( - kt^n )

n = 2.3

t = 145 secs

reaction = 50% after t = 145 secs

Reaction = 88% after t = ?

attached below is a detailed solution
