Above is a potential energy curve of a reaction. It depicts conversion of reactant to product via transition state.
When a catalyst is added to the reaction system, energy barrier of reaction decreases.
It must be noted that energy barrier reaction is defined as energy difference between reactant and transition state.
In present case, energy of reactant is 200 kj, while that of transition state (in absence of catalyst) is 650 kj
Thus, energy barrier of reaction is 650 - 200 = 450 kj
<span>Hence, system must absorb 450 kj of energy for the reaction to start, if no catalyst was used</span>
Explanation:
If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation
Answer:
There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. There are variations, though, as other factors such as elevation, ocean currents, and precipitation affect climate patterns.
