Question 1
1 / -0

In a reaction 2A + B → A₂B, the reactant A will disappear at

A
Half the rate that B will decrease

B
The same rate that B will decrease

C
Twice the rate that B will decrease

D
The same rate that A₂B will form

Solution

The rate of a reaction depends upon concentration of reactant.
Question 2
1 / -0

The rate of disappearance of SO₂ in the reaction 2SO₂ + O₂ → 2SO₃is 1.28 × 10^-3 g/sec then the rate of formation of SO₃ is

A
0.64 × 10^-3 g/sec

B
0.80 × 10^-3 g/sec

C
1.28 × 10^-3 g/sec

D
1.60 × 10^-3 g/sec

Solution

Catalyst increases the rate by decreasing the activation energy.
