List of top Chemistry Questions on Order of Reaction asked in AP EAPCET

At \(1130\,K\), the decomposition of ammonia on Pt catalyst follows zero order kinetics. The rate of this reaction at \(t=10\) min is \(x\ mol\,L^{-1}\,min^{-1}\). What will be its rate (in \(mol\,L^{-1}\,min^{-1}\)) at \(t=20\) min, at the same temperature?
For a first-order reaction, the concentration of a reactant decreases from 0.8 M to 0.4 M in 20 minutes. What is the half-life of the reaction? (Use $\ln 2 = 0.693$)

For a first-order reaction, the concentration of reactant was reduced from 0.03 mol L\(^{-1}\) to 0.02 mol L\(^{-1}\) in 25 min. What is its rate (in mol L\(^{-1}\) s\(^{-1}\))?
