Answer #1

There is a chance of occurance of reaction even when the concentration of reactant on the catalyst surface is zero.

The rate of reaction is independent on concentration of reactant in case of zeroth order reactions. Then there is a possibility of reaction.

In some mechanisms the catalyst is required only till the intermediate cpmpound is formed. If the intermediate concentration in free space is non zero the possibility of reaction occurance can be observed even when the reactant concentration on catalyst surface is zero.

Suppose a reaction with a single reactant is first order in that reactant. As a first-order reaction, the concentration of the reactant will decrease exponentially with time, and its half-life will be constant. Does the fraction of molecules that react per unit time change as the reaction progresses? Justify your answer. please justify with words and not just equations.

Consider the following reaction which follows zero-order reaction kinetics           A(g) + Catalyst(s) ? B(g)                ?H = -226.9 kJ Notice that the reaction is exothermic, so in a closed system it is possible for this to get out of hand: The reaction releases energy, which increases the temperature, which increases the rate, which makes it heat up faster, which makes it react faster

How does collision theory explain the effect of concentration on reaction rate? The reaction rate depends on the sum of the reactant concentrations. The reaction rate depends on the sum of the product concentrations. The reaction rate depends on the product of the product concentrations. The reaction rate depends on the product of the reactant concentrations.
