In the first step of the ostwald process for the synthesis of nitric acid, ammonia is converted to nitric oxide by the high-temperature reaction 4 nh31g2 + 5 o21g2 ¡ 4 no1g2 + 6 h2o1g2 (a) how is the rate of consumption of o2 related to the rate of consumption of nh3? (b) how are the rates of formation of no and h2o related to the rate of consumption of nh3

Solution: The given balanced equation is:

If we have a hypothetical equation:

Then the rate could be written as:

From above expression one thing could easily be noticed that the coefficients of all are inverted. Also, there is negative sign in front of reactants and positive sign in front of the products. Negative sign stands for rate of consumption where as positive sign stands for rate of formation.

Like the above example, we can write the rate for the given equation and it would be looking as:

Now we can easily answer all the parts of the question.

(a) From above expression, the rate of consumption of related to rate of consumption of as:

multiply both sides by -5

So, rate of consumption of oxygen is the rate of consumption of ammonia.

(b) The relationship between rate of formation of NO to the rate of consumption of ammonia will be written as:

Multiply both sides by 4

So, rate of formation of NO equals to the rate of consumption of ammonia.

Now, the rate of formation of to the rate of consumption of ammonia would be:

Multiply both sides by 6

So, the rate of formation of is times that is 1.5 times to the rate of consumption of ammonia.

distance, luminosity, brightness, radius, chemical composition, and temperature

it's all four options.
