CHEMICAL EQUILIBRIUM
Multiple Questions from Chemical Equilibrium
1.Chemcal equilibrium is a _________ equilibrium (a)- dynamic (b)- static (c)- either(a) or (b) (d)- none 2.H2 + I2 ↔ 2HI .If Kc/sub> for this equilibrium is 64 , its Kp is , (a) -1/64
(b)- 64
(c)- either(a) or (b)
(d)- none 3. A system reaches chemical eqiulibrium when (a)-no new product is formed by the forward reaction
(b)-the reverse reaction no longer occurs in the system
(c)-the concentration of reactants in the system is equal to that of the products (d)-the rate at which the forward reaction occurs equals to that of the reverse reactio
4.What does the value of Kp greater than 1 mean ?
(a)more reactants than products exist in at equilibrium
(b) more products than reactants exist in at equilibrium
(c)the rate of forward reaction is high at equilibrium
(d)the rate of reverse reaction is high at equilibrium 5. The following system is in equilibrium : 2S(s) + 5F2(g) ↔ SF4(g> + SF6(g>
The equilibrium will shift to the right if _______
