We're asked to determine the rate of reaction of the hydrogenation of ethylene if it follows a zero-order reaction mechanism:
Recall that the rate law only focuses on the reactant concentrations and has a general form of:
k = rate constant
A & B = reactants
x & y = reactant orders
For a zero-order mechanism, reactant orders = 0, which means:
In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.55 mol . L-1 and its rate constant (k) is 0.0014 mol . L-1 . s-1.
Determine the rate of reaction if it follows a zero-order reaction mechanism. Express your answer to two significant figures and include the appropriate units.
