Answer:
Explanation:
a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional ammonia will be produced .
b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.
c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³
d ) Substituting the given values in the equation ,
Keq = [ 6M ] ² / [ 3M] [ 4M]³
= 36 / 3 x 64 M⁻²
= 18.75 x 10⁻² M⁻² .
Answer:
The potential energy is 9800 J.
Explanation:
given information:
mass, m = 50 kg
height, h = 20 m
to calculate the potential energy, we can use the following formula
PE = mgh
where
PE = potential energy (Joule)
m = mass (kg)
h = height (m)
g = gravitational constant (9.8 m/s²)
so,
PE = mgh
= 50 x 9.8 x 20
= 9800 J
