Thermal energy will flow from an object high temperature to an object of low one. In this case, the thermal energy will flow from object B to object A.
<u>Answer:</u>
<em>The sign of work for this process will be Negative.</em>
<em></em>
<u>Explanation:</u>
Work done by the system on the surroundings is negative
So, If work is done on the system, its sign is positive. If work is done by the system, its sign is negative
Here we see the system that is argon gas is expanding and the work is done by the system into the surroundings (vessel) and the sign is Negative
Therefore, the sign of work for this process will be Negative.
Answer:
The pressure of H₂(g) = 741 torr
Explanation:
Given that:
The atmospheric pressure measured in the lab = 765 torr
The vapor pressure of water = 24 torr
By applying Dalton's Law of Partial Pressure :
Making The Pressure inside the tube due to the H₂(g) the subject of the formula :
we have:
= (765 -24) torr
= 741 torr
Therefore; the pressure of H₂(g) = 741 torr
The answer to your question would be _B High Temp
Answer:
C. Increase the temperature, allowing more frequent collisions of A and B with greater kinetic energy.
Explanation:
For the reaction:
A + B → 2C
You can increase the consume of A:
A. Utilize reaction conditions to convert both reactants to solids. <em>FALSE. </em>Convert both reactants in solids makes less frequent collisions doing difficult the reaction.
B. Decrease the concentration of reactant B to allow C to be produced at a greater rate. <em>FALSE. </em>The decreasing of B will make the reaction slowly.
C. Increase the temperature, allowing more frequent collisions of A and B with greater kinetic energy. <em>TRUE. </em>The increase of temperature will make more frequent collisions of A and B doing the reaction faster.
D. Increase the concentration of C to allow for more frequent collisions of A and B of higher energy
. <em>FALSE. </em>The increase of C makes less frequent collisions doing difficult the reaction.
E. Introduce a catalyst to decrease the consumption of A and B. <em>FALSE. </em>Introducing a catalyst increase the consumption of A and B.
I hope it helps!
