Question: Please Help 1. A reaction has a first-order rate constant of 6.2910 5 s 1 at 25 C and 0.00164 s 1 at 79 C.

Please Help

1. A reaction has a first-order rate constant of 6.2910⁵ s¹ at 25 C and 0.00164 s¹ at 79 C. What is the value of the rate constant at 57 C? Enter your answer in units of s¹, accurate to three significant figures.

2. For the elementary process below, the activation energy is 43 kJ mol¹ and the enthalpy of reaction is 22 kJ mol¹. What is E_a for the reverse process, in kJ mol¹ ? A + B AB

3. Consider the reaction A B which is endothermic in the forward direction. Which of the following increase(s) when the temperature increases.You may select more than one, or none, of the options.

		E_a(reverse)
		the reverse rate
		the forward rate
		E_a(forward)
