In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.50 mol * L−1 and its rate constant (k) is 0.0016 mol * L−1 * s−1.
a. Determine the rate of reaction if it follows a zero-order reaction mechanism.

Where the minus sign represents that the reagent is disappearing, k is the rate constant, which depends on the temperature, and n is the order of the reaction. For the reaction with more than 1 reagent, each reagent will have its order, which is determined by experiments. So, for n = 0:

-r = 0.0016*(1.50)⁰

-r = 0.0016 mol/(L.s)

In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.50 mol * L−1 and its rate constant (k) is 0.0016 mol * L−1 * s−1. a. Determine the rate of reaction if it follows a zero-order reaction mechanism.
