At a certain concentration of H2 and NH3, the initial rate of reaction is 0.120 M / s. What would the initial rate of the reaction be if the concentration of H2 were halved

The question is incomplete, here is the complete question:

The rate of certain reaction is given by the following rate law:

At a certain concentration of

As we are given that:

Initial rate = 0.120 M/s

Expression for rate law for first observation:

....(1)

Expression for rate law for second observation:

....(2)

Dividing 2 by 1, we get:

Therefore, the initial rate of the reaction will be, 0.03 M/s

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
