The decomposition of nobr is studied manometrically because the number of moles of gas changes; it cannot be studied colorimetrically because both nobr and br2 are reddish-brown. 2nobr(g) →2no(g) + br2(g) use the data below to make the following determinations: (a) the average rate of decomposition of nobr over the entire experiment. (b) the average rate of decomposition of nobr between 2.00 and 4.00 seconds. time (s) [nobr] (mol/l)0.00 0.01002.00 0.00714.00 0.00556.00 0.00458.00 0.003810.00 0.0033the rates of decomposition of nobr are

a) 6,7x10⁻⁴M/s

b) 8,0x10⁻⁴M/s

Explanation:

a) You can determine the average rate of descomposition calculating the ratio of change of concentration to change of time.

For the entire experiment:

t=0,00→ 0,0100M

t=10,00→0,0033M

= 6,7x10⁻⁴M/s

b) Between 2,00 and 4,00 seconds:

t=2,00→ 0,0071M

t=4,00→0,0055M

= 8,0x10⁻⁴M/s

I hope it helps!

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
