Answer:
Independent
Explanation:
Independent Variable is the volume of the object. Dependent Variable is the mass of the object. So it
Answer:
(a) False;
(b) False;
(c) False;
(d) True.
Explanation:
(a) When equilibrium is reached, the forward reaction rate becomes equal to the reverse reaction rate, that's why the molarity of each species remains constant, but reactions don't stop.
(b) According to the principle of Le Chatelier, an increase in molarity of either reactants or products would lead to a disturbance of equilibrium. This disturbance would lead to the shift of equilibrium towards the side which would minimize such a disturbance.
(c) Equilibrium constant is only temperature-dependent, it's independent of molarity, pressure, volume etc. of any species present in the reaction.
(d) The greater the initial molarity of reactants, the more products can be formed, e. g., since the ratio of products to reactants should be kept constant, the larger the amount of reactants, the greater the amount of products formed to keep a constant ratio.
Answer:
2.56 eV
Explanation:
Using the formula;
ΔE= -RH(1/n^2final - 1/n^2initial)
RH = -2.18 * 10-18 J
nfinal = 2
ninitial =1
Substituting values;
ΔE= -2.18 * 10-18 J(1/4^2 - 1/2^2)
ΔE= -2.18 * 10-18 J(0.0625 - 0.25)
ΔE= 4.09 * 10^-19 J
To convert to eV
4.09 * 10^-19 J/1.6 * 10^-19
=2.56 eV
