An enzyme-catalysed reaction has E_a = 80 kJ mol^-1 without the enzyme and 50 kJ mol^-1 with it, at 300 K. Take R = 8.31

Question

An enzyme-catalysed reaction has E_a = 80 kJ mol^-1 without the enzyme and 50 kJ mol^-1 with it, at 300 K. Take R = 8.314 J mol^-1 K^-1, equal pre-exponential factors, and the enzyme lowering the reverse activation energy by the same amount. Select the correct statements.

Accepted Answer

The forward rate constant increases by more than a factor of 10^5.

Accepted Answer

The rate constant of the reverse reaction also increases by the same factor as the forward one.

Answer

The forward rate constant increases by less than a factor of 10^4.

Answer

The enthalpy change of the reaction becomes 30 kJ mol^-1 more negative.

An enzyme-catalysed reaction has $E_{a} = 80 kJ mo l^{- 1}$ without the enzyme and $50 kJ mo l^{- 1}$ with it, at $300 K$ . Take $R = 8.314 J mo l^{- 1} K^{- 1}$ , equal pre-exponential factors, and the enzyme lowering the reverse activation energy by the same amount. Select the correct statements.
