Why ddo all collisions between reactant molecules not lead to reaction.
jok3333 [9.3K]

Answer:

The colliding molecules need to possess certain energy which is greater than the activation energy Ea and proper orientation.

<h3>Not all collisions result in a chemical reaction because not all collisions have the have sufficient amount of energy or have the appropriate activation energy. Nor do they all have this correct orientation. Molecules need to collide in such a way that they're oriented, so the correct bonds could break in. The correct bonds conform. And then, of course, they need to have sufficient activation energy in order to initiate the breaking of the bonds.</h3>

<h3>Hope this helps please let me know If I'm wrong.</h3>

lawyer [7]

Answer:

Option C; NONE.

Explanation:

A chemical reaction forms new chemicals called the products from the initial chemicals called the reactants. The reaction between an acid and a base is called neutralization, and the products formed are water and a salt.

When hy­drochlo­ric acid and sodi­um hy­drox­ide is mixed together, they in­ter­act, and re­sult­ in salt and a release of heat.

The re­sult of the in­ter­ac­tion of these two high­ly ag­gres­sive com­pounds is ta­ble salt and wa­ter, these resulting com­pounds are ul­ti­mate­ly harm­less, and even ben­e­fi­cial, to hu­man be­ings.

Therefore, NO TOXIC GAS WOULD BE FORMED BY MIXING HYDROCHLORIC ACID WITH SODIUM HYDROXIDE.
