Nitrogen monoxide, NO, reacts with hydrogen, H2, according to the following equation. 2 NO + 2 H2 → N2 + 2 H2O What would the rate law be if the mechanism for this reaction were as follows? (Rate expressions take the general form: rate = k . [A]a . [B]b.) 2 NO + H2 → N2 + H2O2 (slow) H2O2 + H2 → 2 H2O (fast)

The rate law for the reaction is

Explanation:

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

For the given chemical reaction:

The intermediate reaction of the mechanism follows:

Step 1:  

Step 2:  

As, step 1 is the slow step. It is the rate determining step

Rate law for the reaction follows:

Hence, the rate law for the reaction is

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
