NEET Chemistry Chemical Kinetics Questions Solved


In the formation or sulphur trioxide by the contact process,

2SO2(g) + O2(g) 2SO3(g)

The rate of reaction is expressed as d(O2)/dt = 2.5x10-4 mol L-1sec-1. The rate disappearance of (SO2) will be

1. 5.0x10-4 mol L-1sec-1

2. 2.5x10-4 mol L-1sec-1

3. 3.75x10-4 mol L-1sec-1

4. 50.0x10-4 mol L-1sec-1

(1) 2SO2 + O2 2SO3(g)

    -1/2dsO2/dt = -dO2/dt

    -dsO2/dt = 2x2.5x10-4 =5x10-4 mol L-1sec-1
