11. A process is spontaneous when the free energy charge is positive
true or false
12. The standard cell potential can be determining by
a)taking the difference between the reduction potenial at the cathod and anode
b)taking the difference between the oxidation potenial at the cathod and anode
c)adding the reduction potentials at the catode and the anode
d)adding the oxidation potentials at the cathode and the anode
30. The more positive the reduction half reaction the easier it is for the substance to be
true or fasle
A diprobic acid will have two equivalence point on its titration curve
true or false
Explanation / Answer
1. False. The van't Hoff factor increases with increasing number of ions of solute but not its concentration.
2.
. If a reaction rate doubles when the concentration of reactants double the rate is
b) first order
3.False
since the rate determining step of a multistep reaction is always the slowest step.
4. False
If a reaction quotient is larger than Kmg then the reaction favors reactants.
5.d)some Bronsted-lowry acids and bases are lewis acids and bases.
6. The product if K2 of H2SO3 and K2 of SO is equal to K
false; it should be different.
7.The Kmg of a salt increases if the salt is dissolved in strongly acidic solution with a common
true as ionic strength will increase. primary and secondary salt effect.
8.
8. A reaction is always spontaneous when
a) the reaction is exothermic and increase entropy.
9.A spontaneous process is irreversible
true.
10.. During melting
a)the temperature does not change however the entropy increases
11.false since
process is spontaneous when the free energy charge is negative.
12.
The standard cell potential can be determining by
a)taking the difference between the reduction potenial at the cathod and anode.
