Answer : The temperature for non-catalyzed reaction will be,
Explanation :
Activation energy : The energy required to initiate the reaction is known as activation energy.
According to the Arrhenius equation,
Since, the rate for both the reaction are equal.
..........(1)
where,
= activation energy for non-catalyzed reaction = 70.0 kJ/mol
= activation energy for catalyzed reaction = 42.0 kJ/mol
= temperature for non-catalyzed reaction = ?
= temperature for catalyzed reaction =
Now put all the given values in the above formula 1, we get:
Therefore, the temperature for non-catalyzed reaction will be,
From the given balanced chemical reaction it is signified that in every 1 mole of H2 will require 2 moles of K. Using the concept of ratio and proportion, with x being the number of moles of H2,
2/1 = 0.3/x
The value of x from the equation, 0.15 moles.
Explanation:
The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.
