Everything else being equal, write a general expression to show how the exchange current density for a reaction changes as a fun
ction of temperature. In other words, write an expression for j0(T) at an arbitrary temperature T as a function of j0(T0) at a reference temperature T0. If a reaction has j0 = 10-8 A/cm2 at 300K and j0 = 10-4 A/cm2 at 600K, what is ∆G1 + + for the reaction? Assume that the T0 is 300K.

Answer:
Gibbs free energy is 45944.86 J/mol
Explanation:
In Engineering, thermodynamics, the Gibbs free energy is a potential that is used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure.

Answer:
a)Wt =25.68 lbf
b)Wt = 150 lbf
F= 899.59 N
Explanation:
Given that
m= 150 lbm
a)
Weight on the spring scale(Wt) = m g
We know that
Wt = 150 x 5.48/32 lbf
Wt =25.68 lbf
b)
On the beam scale
This is scale which does not affects by gravitational acceleration.So the wight on the beam scale will be 150 lbf.
Wt = 150 lbf
If the plane is moving upward with acceleration 6 g's then the for F
F = m a
We know that
a=6 g's
So
F = 90 x 9.99 N
F= 899.59 N
Answer:
Explanation:
Given data:
flow rate = 10 gallon per minute = 0.0223 ft^3/sec
diameter = 0.75 inch
we know discharge is given as
Q = VA
solve for velocity V = \frac{Q}{A}[/tex]
V = 7.27 ft/sec
we know that Reynold number
calculate the ratio to determine the fanning friction f
from moody diagram f value corresonding to Re and is 0.037
for horizontal pipe
where 1.94 slug/ft^3is density of water
