Answer:
Explanation:
Given
Required
Convert to meters per minutes
Start by converting the speed from miles to meters
So, we have:
Next, we convert time from hours to minutes
So, we have:
<em>Hence, the equivalent of 25 miles per hour is 670.56 meters per minutes</em>
Answer:
Sufficient concentration and correct orientation of particles
Explanation:
The collision theory postulates that, for a chemical reaction to occur, there must be collision between reacting particles.
It implies that the rate of reaction depends on the number of collisions per unit time as well as the fraction that are successful or effective.
For collisions to be effective, there must be proper orientation of the particles and right concentration of the reactants.
- The number of effective collisions and rate of reaction are directly proportional to the concentration of of the reactants.
It’s a process called ginning
