Is there any reaction for which the rate does not decreases with time?

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

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) .

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 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.

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

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