I would say the answer is C
Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
Answer:
The Sun is the closest star to Earth.
Given :
Length , l = 59.8 m.
Breadth , b = 26.6 m.
Depth , d = 3.7 ft .
Density of water ,
.
To Find :
Mass of water in pool .
Solution :
First we will covert depth into m from ft .

For ,

So , volume of pool is :

We know , density is given by :

So , 
Putting given values in above equation :

Hence , this is the required solution.
