Ответ:
1. False
2. False
3.![2AB_2(g)\rightarrow 2A_2(g)+B_2(g)](/tpl/images/0497/5342/bbc79.png)
Explanation:
1. Chemical equilibrium are attained is closed system.
The macroscopic properties remain constant like: volume, pressure, energy etc. Rate of forward reaction is equal to the rate of backward reaction.
The concentration of the reactants and products remain constant.They are not always equal.
2.![A+B\rightleftharpoons heat+AB](/tpl/images/0497/5342/c69fe.png)
By increasing the temperature:
If the temperature is increased, so according to the Le-Chatelier's principle , the equilibrium will shift in the direction where decrease in temperature occurs. As, this is an exothermic reaction, backward reaction will decrease the temperature. Hence, the equilibrium will shift in the left direction (i.e. towards reactants.)
3. If the pressure of the container is increased, the pressure will decrease according to Boyle's Law. Now, according to the Le-Chatelier's principle, the equilibrium will not shift in any direction when the number of moles of gas molecules is equal at the product side and the reactant side.
Ответ:
C) f(-3) = g(-3)
Step-by-step explanation:
This is the answer because the lines intersect at the point (-3, -4). When you plug in the x-value of -3 into both equations, the y-value will be equal.
