For the reaction: 2 h2 + 2 no → n2 + 2 h2othe observed rate expression, under some conditions, is: rate = k[h2][no]which of the following mechanisms are consistent with these data? select all that are true. step 1 2 no → n2o2 (slow) step 2 n2o2 + h2 → n2o + h2o (fast) step 3 n2o + h2 → n2 + h2o (fast)step 1 no + no ⇌ n2o2 (fast) step 2 n2o2 + h2 → n2 + h2o + o (slow) step 3 o + h2 → h2o (fast)step 1 2 no ⇌ n2o2 (fast) step 2 n2o2 + h2 → n2o + h2o (slow) step 3 n2o + h2 → n2 + h2o (fast)step 1 h2 + 2 no → n2o + h2o (slow) step 2 n2o + h2 → n2 + h2o (fast)

The correct mechanism for the reaction based on the given rate is:

Step 1 :

Step 2:

Explanation:

The reaction rate of a muti-step reaction is determined by the slowest step of the reaction. Because of this reason, it is known as the rate-determining step of the reaction.

The given rate expression has the concentrations of .

This means that the slowest step of the mechanism must involve .

Among the proposed mechanisms, this criterion is met in the mechanism:

( Reason: In the above mechanism the slowest step involves . )

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?
