हिन्दी The given graph is a representation of kinetics of a reaction. The y and x axes for zero and first order reactions, respectively are:
- zero order (\( y = \text{rate} \) and \( x = \text{concentration} \)), first order (\( y = t_{1/2} \) and \( x = \text{concentration} \))
- zero order (\( y = \text{rate} \) and \( x = \text{concentration} \)), first order (\( y = \text{rate} \) and \( x = t_{1/2} \))
- zero order (\( y = \text{concentration} \) and \( x = \text{time} \)), first order (\( y = t_{1/2} \) and \( x = \text{concentration} \))
- zero order (\( y = \text{concentration} \) and \( x = \text{time} \)), first order (\( y = \text{rate constant} \) and \( x = \text{concentration} \))
Correct answer · Option 1
zero order (\( y = \text{rate} \) and \( x = \text{concentration} \)), first order (\( y = t_{1/2} \) and \( x = \text{concentration} \))
Explanation
For a zero-order reaction, rate is independent of concentration, or concentration changes linearly with time. For a first-order reaction, half-life \( t_{1/2} = 0.693/k \) is independent of concentration.
