If the reaction fe2n(s)+32h2? 2fe(s)+nh3(g)comes to equilibrium at a total pressure of 1 bar, analysis of the gas shows that at 700. and 800. k, pnh3/ph2 = 2.165 and 1.083, respectively, if only h2(g) was initially present in the gas phase and fe2n(s) was in excess. calculate kp at 700. k. calculate kp at 800. k. calculate ? h? r assuming that it is independent of temperature. calculate ? s? r at 700. k. calculate ? s? r at 800. k. calculate ? g? r for this reaction at 298.15 k.

the answer is 0.42 is that is an option. this question provides no info

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.
