The formation of gas at the surface of tungsten due to adsorption is a reaction of which order?

The rate of a certain reaction depends on concentration according to the equation $-dc/dt = (K_1 C) / (1 + K_2 C)$. What is the order when concentration $(C)$ is very high?

The half-life period for a certain zero-order reaction is $10 \text{ min}$. How much time is required for this reaction to complete $100\%$ (in $\text{ min}$)?

The plot of concentration of a reactant versus time for a chemical reaction is shown below. The order of this reaction with respect to the reactant is
