Question

In a given graph of zero-order reaction, the slope and intercept are:

Options

• Slope = k, Intercept = [R]₀

• Slope = −k, Intercept = [R]₀

• Slope = `k/2.303`, Intercept = In[R]₀

• Slope = `−k/2.303`, Intercept = In A

Answer 1

Slope = −k, Intercept = [R]₀

Explanation:

According to the integrated rate law for zero order:

[R] = −kt + [R₀]

So the slope is equal to the negative of rate constant −k and the intercept is equal to the initial concentration R₀.
