Is there any reaction for which reation rate does not decrease with time ?

The rate of a zero reaction does not change with time. Explain.

For a chemical reaction R rarr P , the rate of reaction does not change when the concentration of R is changed. What is the order of reaction ?

Each question contains STATEMENTS-1 (Assertion) and STATEMENT -2 (Reason). Examine the statements carefully and mark the correct answer according to the instructions given below: STATEMENT-1: For exothermic reaction equilibrium constant decrease with increase in temperature. STATEMETN-2: For exothermic reaction rate constant decrease with decrease in temperature.

The rate of a reaction increases four times when the temperature changes from 300 K to 320 K. Calculate the energy of activation of the reaction assuming that it does not change with temperature (R = 8.314 JK^-1 mol^-1) .

The rate of a reaction quadruples when the temperature changes from 293 K to 313 K. Calculate the energy of activation of the reaction assuming that it does not change with temperature.

A zero order reaction is one in which the rate of reaction:

k_(34^(@))/k_(35^(@)) lt 1 , then : a) Rate increase with the rise in temperature b) rate decrease with rise in temperature c) rate does not change with rise in temperature d) None of the above

For a chemical reaction A rarr B ,it is observed that the rate of reaction doubles when the concentration of A is increased four times. The order of reaction in A is :

Why the rate of physical adsorption decreases with the rise of temperature ?
