Eley-Rideal reactions over rough surface: effect of sticking probability

Eley-Rideal reactions are analyzed over rough surface of random deposition model. Different sticking probabilities viz. 1, 0.7, 0.4 and 0.1 of the reacting particles are considered. Reaction probability distributions are transformed into a useful compact form through the multifractal scaling analysis. Range of reaction probability decreases with decrease in sticking probability. The non-linearity in the q-τ(q) multifractal plots and range of α values in α-f(α) multifractal plots increases with an increase in sticking probability indicating greater heterogeneity in the reaction probability distribution with an increase in sticking probability where q is the moment order, τ(q) is the scaling exponent, α and f(α) are the characteristic scaling exponents for reaction probability distributions.
