Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Explanation:

According to the standard conversion,

$1 Joule = 0.000239006 kcal$

Therefore, 675,000 Joules will be converted into kcal as follows.

$1 Joule = 0.000239006 kcal\\675,000 J = 675000 J \times \frac{0.000239006 kcal}{1 J}\\= 161.328872 kcal$

Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Answer:

The maximum kinetic energy of electron is = 2.93 × $10^{-19}$ Joule

Explanation:

We know that total energy

$E = \frac{hc}{\lambda}$ ------------ (1)

Here h = plank's constant = 6.62 × $10^{-34}$ J s

c = speed of light = 3 × $10^{8}$ $\frac{m}{s}$

$\lambda$ = 261 nm = 261 × $10^{-9}$ m

Put all these values in equation (1) we get

E = 7.6 × $10^{-19}$ J

We know that

Total energy = Energy to remove an electron + K.E of electron

Energy to remove an electron = $\frac{281.7 (1000)}{(6.023)10^{23} }$

Energy to remove an electron = 4.67 × $10^{-19}$ J

K.E of electron = Total energy - Energy to remove an electron

K.E of electron = 7.6 × $10^{-19}$ - 4.67 × $10^{-19}$

K.E of electron = 2.93 × $10^{-19}$ Joule

Therefore the maximum kinetic energy of electron is = 2.93 × $10^{-19}$ Joule
