In a reversible reaction, increase in pressure favours that reaction where the number of moles
Decreases
Increases
Remains same
First increases then decreases
The rate of a reaction is doubled or tripled, when temperature increase to
20°
30°
40°
10°
The rate of a reaction is expressed in terms of
moles litre
moles/litre
moles/litre/second
moles second
A white precipitate formed when barium chloride reacted with sodium sulphate solution is
NaCl
BaO2
BaSO4
NaOH
Substance which is capable of altering the rate of a reaction without undergoing any chemical change is called a
Reactant
Product
Catalyst
Solvent
The substances obtained after the completion of a chemical change is known as
Solute
Reactions in which the products cannot be reconverted into starting material is
Reversible reaction
Displacement reaction
Irreversible reaction
Combination reaction
The rate of a reaction depends on
Nature of reactants
Nature products
Nature of reaction condition
Reactivity
Moderate reactions are those which takes place in
Several hours
Few minutes
Fraction of second
Several days
The substances which is used as a starting material for a chemical reaction is called
