Reactions in which the products cannot be reconverted into starting material is
Reversible reaction
Displacement reaction
Irreversible reaction
Combination reaction
The substances which is used as a starting material for a chemical reaction is called
Solute
Solvent
Reactant
Product
When rate of forward reaction is equal to the rate of backward reaction, the system is said to be in a state of
Zero reaction
Equilibrium
Constant motion
None of these
The catalyst used in the decomposition of H2O2 in
FeCl3
Fe2O3
FeCl2
Fe(OH)3
H2 +I2 ↔ 2HI When pressure is increased, the equilibrium
Unaffected
Increases
Decreases
Zero
Hydrolysis of methyl acetate gives an acid
Methanoic acid
Methyl alcohol
Acetic acid
Acetone
In a reversible reaction, increase in pressure favours that reaction where the number of moles
Remains same
First increases then decreases
Reactions which takes place in several hours and above are known as
Moderate reaction
Fast reaction
Slow reaction
Very slow reaction
Moderate reactions are those which takes place in
Several hours
Few minutes
Fraction of second
Several days
