A certain reaction with an activation energy of 185 kJ/mol was run at 525 K and again at 545 K . What is the ratio of f at the h
Kazeer [188]

Answer: The ratio of f at the higher temperature to f at the lower temperature is 4.736

Explanation:

According to the Arrhenius equation,

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

or,

\log (\frac{f_2}{f_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]

where,

f_1 = rate constant at 525K

K_2 = rate constant at 545K

Ea = activation energy for the reaction = 185kJ/mol= 185000J/mol   (1kJ=1000J)

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 525 K

T_2 = final temperature = 545 K

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

\log (\frac{f_2}{f_1})=\frac{185000J/mol}{2.303\times 8.314J/mole.K}[\frac{1}{525K}-\frac{1}{545K}]

\log (\frac{f_2}{f_1})=0.6754

(\frac{f_2}{f_1})=4.736

Therefore, the ratio of f at the higher temperature to f at the lower temperature is 4.736

Strzała o masie 20g tuz po wystrzale ma prędkość 50m/s. Oblicz pracę wykonana przez zawodniczkę. Ile wynosi energia potencjalna
garri49 [273]

Answer:

Explanation:

masie m = 20g = 20/1000 = 0.02kg

prędkość v = 50m/s

P.E = K.E = ½mv²

P.E = ½ × 0.02 × 50²

P.E = 25 J

pracę wykonana = P.E = 25J

A wire 43.7 cm long carries a 0.450 A current in the positive direction of an x axis through a magnetic field with an x componen
zubka84 [21]

Answer: Force on a current-carrying wire

F = I L x B

where F, L and B are all vectors, x means cross product.

I = 0.410 A

L = (0.689, 0, 0) m

B = (0, 0.000330, 0.0110) T

F = 0.410*(0.689, 0, 0) x (0, 0.000330, 0.0110) N

= (0, -0.410*0.689*0.0110, 0.410*0.689*0.000330)

= (0, -3.11*10^-3, 9.32*10^-5) N

so

a) Fx = 0

b) Fy = -3.11*10^-3 N

c) Fz = 9.32*10^-5 N
