Remains unaffected

Can either increase or decrease (depends on the type of catalyst)

Decreases

ND = (n + 1)/2

None of these

ND = n/2

When rate expressions are very simple

When the data are scattered

None of these

For testing complicated mechanisms

Use CSTR with a high conversion, when a > b

Avoid recycle, when a > b

Use batch reactor or plug flow reactor, when a > b

Use high pressure and eliminate inerts, when a > b
