Consider the following reaction: 2 H2(g) + 2 NO(g) → 2 H2O(g) + N2(g) If the concentration of NO changed from 0.100 M to 0.025 M in the first 15 minutes of the reaction, what is the average rate of the reaction during this time interval?

The average rate of the reaction during this time interval is, 0.005 M/s

Explanation:

The given chemical reaction is:

The expression will be:

where,

= final concentration of = 0.025 M

= initial concentration of = 0.100 M

= final time = 15 minutes

= initial time = 0 minutes

Putting values in above equation, we get:

Hence, the average rate of the reaction during this time interval is, 0.005 M/s

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
