Consider the following equilibrium.2 nobr(g)< => 2 no(g) + br2(g)if nitrosyl bromide, nobr, is 34 percent dissociated at 25°c and the total pressure is 0.25 atm, calculate kp and kc for the dissociation at this temperature.

of the reaction is  .

of the reaction is  .

Explanation:

Initial pressure of NOBr is "x" atm.

34% = 0.34

The equilibrium chemical reaction is a follows.

Initial          x                                      0          0

Change    -0.34x                             +0.34x    +0.17x

Final        (x-0.34x)                          +0.34x     +0.17x

Total pressure = sum of the pressure at equilibrium.

Partial pressure of NOBr=  x-0.34x =x (1-0.34)

= 0.213(0.66) = 0.14 atm.

Hence, partial pressure of is 0.14 atm.

From equation (1)

Therefore, of the reaction is  .

Rearrange the equation is as follows.

= number of moles of reactants - Number of moles of products

= 3-2 = 1

Therefore, of the reaction is  .

the answer is   c.) 1575 j.

explanation:

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
