Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
Answer:
sing a battery with a higher voltage:
✔ stronger force of attraction
Wrapping the wire around the nail only three times:
✔ weaker force of attraction
Changing the direction of the current by reversing the battery connections:
✔ no change
Using a plastic stick in place of the iron nail:
✔ weaker force of attraction
Holding the nail vertically rather than horizontally:
✔ no change
Explanation: You're Welcome
Answer:
New temperature t2 = [1.28T− 273.15]° C
Explanation:
Given:
Volume v1 = 25 gram
New volume v2 = 25 + 7 = 32 gram
Constant pressure = p
Temperature t1 = T
Find:
New temperature t2
Computation:
Pv1/t1 = Pv2/t2
25 / T = 32 / t2
t2 = 1.28T
New temperature t2 = [1.28T− 273.15]° C
Kinetic energy has increased.
The <em>Kinetic Molecular Theory</em> of gases states that the average kinetic energy of the molecules of a gas is directly proportional to its Kelvin temperature.
Thus, if the temperature of the air in a room has increased, the average kinetic energy of its molecules has increased.
