In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.65 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.

.0014 M/s ( (mol*L^-1 / s) )

Explanation:

Since the rate law of a zero order reaction is Rate = k[A]^0, the rate is .0014 * (1.65)^0 = .0014

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
