All four answers are right 100%.
The frequency of collisions between the N₂ and H₂ molecules will decrease and the rate of reaction will also decrease.
Since the water is cooler than the gas mixture, heat will flow from the gas to the water.
The gas will cool down, so the average kinetic energy of the gas molecules will decrease.
The molecules will be moving more slowly, so there will be <em>fewer collisions</em> and <em>fewer of these collisions will have enough energy to react</em>.
The rate of reaction between H₂ and N₂ molecules at room temperature is exceedingly slow, <em>but cooling the gas mixture will make the reaction even slower</em>.

<h3>What is pH?</h3>
pH value tells us about the acidity and basicity of any solution. pH means potential hydrogen.
The pH scale is counted from 0 to 14 in which 7 is neutral and the value of pure water.
Below 7 are all acids and the above 7 are all basic.
Thus, all acidic substances are Cola-flavored soda: 2. 6, pickle juice: 5. 5, cranberry juice: 2. 9.

Answer:
1160 kJ/mol
Explanation:
To get the enthalpy of the reaction take ΔH products- ΔH reactants
It changes because when the 2 tectonic plates collide they form mountains and volcanoes.
Continental drift causes tectonic plates to either "pull apart" or "crash" into each other.
Plates that crash into each other either form mountains, or when one slides under the other (a subduction zone) volcanoes from.
