Concentration of reactants is one of the factors influencing the reaction rate. More the concentration, more will be the reaction rate.
The rate-determining step in a chemical reaction is the slowest step that determines the overall rate of the reaction. It sets the pace for the entire process and influences the energy diagram by determining the activation energy required for the reaction to occur.
The rate of a reaction can change significantly with pH. In general, for every unit change in pH, the reaction rate can change by a factor of 10. So, if the pH changes from 6.5 to 2, the rate of the reaction could potentially increase by a factor of 10^4 = 10,000.
To determine the order of a reaction from a table, you can look at how the rate of the reaction changes with the concentration of reactants. If doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant. If doubling the concentration quadruples the rate, the reaction is second order. And if doubling the concentration increases the rate by a factor of eight, the reaction is third order.

Halving the concentration of H2 will decrease the rate of the reaction, assuming it is a first-order reaction with respect to H2. Since the rate law is rate = k[NO]^2[H2], cutting the concentration of H2 in half will decrease the rate of the reaction by a factor of 0.5.
Substrate concentration refers to the amount of substrate present in a chemical reaction. It is a key factor that influences the rate of a reaction, as higher substrate concentrations typically lead to an increase in reaction rate until the enzyme becomes saturated.

surface area has simple constant factor with the rate of reaction. Rate = (surface area)[concentrations with coefficients] the greater the surface area the greater the rate of reaction in a simple constant multiple.
In very fast heterogeneous reactions, the controlling factor is typically the rate of mass transfer of reactants to the reaction surface, rather than the intrinsic chemical reaction rate at the surface. This is because the reaction rate is limited by how quickly reactants can reach the surface and participate in the reaction. Improving mass transfer, for example by increasing surface area or stirring the system, can enhance the overall reaction rate.
The rate of a reaction can change significantly with pH. In general, for every unit change in pH, the reaction rate can change by a factor of 10. So, if the pH changes from 6.5 to 2, the rate of the reaction could potentially increase by a factor of 10^4 = 10,000.
Catalysts can affect the reaction rate by providing an alternate reaction path with lower activation energy. This allows the reaction to proceed faster by requiring less energy to overcome the barrier.

The concentration of reactants is the factor that most significantly affects the rate of reaction. Increasing the concentration of reactants typically leads to more frequent and successful collisions between particles, resulting in a higher reaction rate.
