Answer:
Reaction B has an enzyme.
Explanation:
In both charts, we can see the energy versus the progress of the reaction. In both charts, reactants and products have the same energy, but chart B has a lower activation energy (The difference in energy between the reactants and the activated complex). This is probably due to the action of an enzyme. Enzymes lower the activation energy in order to increase the reaction rate as we can see in the Arrhenius equation.
where,
k is the rate constant
A is the collision factor
Ea is the activation energy
R is the ideal gas constant
T is the absolute temperature
The higher the rate constant, the higher the reaction rate.
Answer:
1. 2.510kJ
2. Q = 1.5 kJ
Explanation:
Hello there!
In this case, according to the given information for this calorimetry problem, we can proceed as follows:
1. Here, we consider the following equivalence statement for converting from calories to joules and from joules to kilojoules:
Then, we perform the conversion as follows:
2. Here, we use the general heat equation:
And we plug in the given mass, specific heat and initial and final temperature to obtain:
Regards!
Answer:
The volume is
Explanation:
From the question we are told that
The number of moles of the gas is
The volume of the gas is
The of moles of the gas that leaked is
Generally from the ideal gas law
Generally at constant pressure and temperature
So
=>
=>
=>
