Chemical Reaction Engineering MCQs

When a catalyst increases the rate of forward reaction, the value of rate constant

In the hydrodealkylation of toluene to benzene, the following reactions occur: C7H8 + H2 → C6H6 + CH4 2C6H6 ⇋ C12H10 + H2 Toluene and hydrogen are fed to a reactor in a molar ratio 1 : 5.80% of the toluene gets converted and the selectivity of benzene (defined as moles of benzene formed/moles of toluene converted) is 90%. The fractional conversion of hydrogen is

Half-life period for a first order reaction is __________ the initial concentration of the reactant.

What is the order of a chemical reaction whose rate is deter-mined by the variation of one concentration term only?

Which of the following curves shows the effect of temperature on the extent of gas-solid adsorption at a given pressure?

Transition state theory gives the rate constant as
