Answer : The concentration of and at equilibrium is, 0.0158 M and 0.00302 M respectively.
Explanation :
First we have to calculate the concentration of
Now we have to calculate the value of equilibrium constant (K).
The given chemical reaction is:
Initial conc. 0.0163 0.00415 0.00276
At eqm. (0.0163-2x) (0.00415+x) (0.00276+x)
As we are given:
Concentration of at equilibrium = 0.00467 M
That means,
(0.00415+x) = 0.00467
x = 0.00026 M
Concentration of at equilibrium = (0.0163-2x) = (0.0163-2(0.00026)) = 0.0158 M
Concentration of at equilibrium = (0.00276+x) = (0.00276+0.00026) = 0.00302 M
In thermodynamics, work of a system at constant pressure conditions is equal to the product of the pressure and the change in volume. It is expressed as follows:
W = P(V2 - V1)
W = 1.3x10^5 (2x6 - 6 )
W = 780000 J
Hope this answers the question. Have a nice day.
Heat will flow from the metal to the water until both are at a temperature somewhere between 20oC and 300oC.
Explanation:
The correct option is that heat will flow from the metal to the water until both are at a temperature somewhere between 200°C and 300°C.
At this point, thermal equilibrium is established in the mixture.
- Heat flows from a body at high temperature to the one with a low temperature.
- Heat will flow from the metal at 300°C to the water at 200°C.
- The heat flow will stop when both the water and aluminium block attains thermal equilibrium.
- This would logically be at a temperature between 200 to 300°C.
- The metal will lose heat and the water will gain heat until both are at a uniform temperature.
